Classification: Not fully assessed, but may include skin irritation, eye irritation, respiratory tract effects; capable of generating dust that can irritate airways Pictograms: If current classification warrants, standard GHS (Globally Harmonized System) pictograms for irritant materials and environment Signal Word: Warning Hazard Statements: Can cause skin and eye irritation, may trigger respiratory discomfort in sensitive individuals; use of proper controls reduces risk Precautionary Statements: Avoid breathing dust, vent work areas; wear protection for skin, eyes, and respiratory tract
Chemical Identity: 1H,5H-Pyrazolo(1,2-A)Pyrazol-1-One, 2,3-Diamino-6,7-Dihydro-, Dimethanesulfonate Purity: Purity often ranges above 95%; trace synthesis reagents may remain Component Breakdown: Principal active component as listed; possible presence of dimethanesulfonate counter-ion and process residues at low concentrations Impurities: Typical reporting includes process solvents, sodium or potassium as minor contaminants depending on raw synthesis reagents Safety Concerns: Unknown impurities may introduce unpredictable risks; proper analytical review before application
Skin Contact: Remove contaminated clothing; wash exposed skin thoroughly using plenty of water and mild soap Eye Contact: Flush eyes under running water for at least fifteen minutes, ensuring eyelids are well rinsed Inhalation: Move person to fresh air; monitor breathing, seek medical advice for any sustained complaints Ingestion: Rinse mouth, offer water if the person is conscious; avoid inducing vomiting; medical attention required for persistent discomfort Note to Physicians: Symptomatic and supportive treatment forms the basis of clinical management; laboratory screening recommended for possible secondary complications
Suitable Extinguishing Media: Water spray, carbon dioxide, dry chemical powder, foam based on fire scale Unsuitable Media: Direct water jets can spread contaminated dust Fire Hazards: Thermal decomposition might produce sulfur oxides, nitrogen oxides, carbon monoxide, and other toxic vapors Protective Equipment for Firefighters: Full protective gear including self-contained breathing apparatus, chemical-resistant suit Firefighting Guidance: Coordinate entry with hazard assessment; prioritize ventilation and containment of runoff
Personal Precautions: Evacuate unnecessary personnel; provide respiratory, eye, and skin protection Environmental Precautions: Prevent product from entering water sources, drains, or soil; alert environmental authorities if accidental release risks contamination Containment Methods: Use wetted inert absorbent material to limit dust, sweep up, and transfer to sealed waste containers; avoid raising dust Cleanup Procedures: Thorough area decontamination with water and non-reactive cleaner; regular air monitoring reduces long-term exposure risk
Safe Handling: Minimize direct contact and dust generation, ensure good laboratory ventilation; all handling performed by trained personnel familiar with risk minimization Storage Requirements: Store product tightly sealed in a cool, dry place out of direct sunlight, isolated from strong oxidizers and acids Special Considerations: Assign storage specifically labeled and separated from food or drink; keep inventory records accurate and updated
Exposure Limits: No established occupational exposure limits; reference generic guidelines for nuisance dust (e.g., 10 mg/m3 for total inhalable, 3 mg/m3 respirable fraction) Engineering Controls: Local exhaust ventilation, dust extraction units, fume hood work strongly recommended Personal Protective Equipment: Nitrile or neoprene gloves, safety goggles or face shield, suitable laboratory coat; use of P2 or P3 filtered dust mask advised for weighing and bulk manipulation Hygiene Measures: Wash hands and face thoroughly after work, change soiled clothing regularly
Appearance: Fine white to off-white crystalline powder or solid Odor: Odorless or faint chemical scent Melting Point/Range: Estimated in the range typical for pyrazolo derivatives (~150-200°C, specification dependent) Boiling Point: Not applicable; decomposes before boiling Solubility: Moderately soluble in water, higher in polar organic solvents Vapor Pressure: Negligible at ambient temperature pH: Water solution shows mild acidity (pH 5-6) due to sulfonate groups Flash Point: Not flammable under standard operations Partition Coefficient n-octanol/water (log Kow): Not determined Density: Unmeasured, estimate based on structural analogues (1.1–1.3 g/cm³) Other Characteristics: Stable under recommended conditions
Chemical Stability: Stable under normal room temperature conditions, protected from moisture and strong light Reactivity: Non-reactive with most laboratory solvents and reagents under standard use Hazardous Reactions: None expected with proper storage, avoid mixing with acids, bases, and powerful oxidants Decomposition Products: Burns or thermal degradation can yield nitrogen oxides, sulfur oxides, and carbon monoxide Incompatibility: Strong oxidizing agents, concentrated acids or bases
Routes of Exposure: Inhalation, skin contact, eye exposure, ingestion Acute Symptoms: May trigger skin or eye irritation, respiratory tract discomfort, throat soreness, or mild headache for sensitive individuals Chronic Effects: Data insufficient for long-term risk assessment; general precautions advised until more evidence accumulates; no evidence for carcinogenicity, mutagenicity, or reproductive toxicity known to date Sensitization: Prolonged exposure without adequate protection may increase risk for sensitization reactions Toxicological Data: No published animal LD50 or LC50 records as of last update; use care until empirical data becomes available
Aquatic Toxicity: Insufficient data; avoid deliberate discharge to waterways owing to possible adverse impact on aquatic organisms Persistence and Degradability: Likely slow degradation; dimethanesulfonate groups known to resist rapid breakdown Bioaccumulation Potential: Structural properties suggest low likelihood for bioaccumulation, but absence of assays means risk cannot be excluded Mobility in Soil: Water solubility can enable some migration in soil; minimize release outside controlled settings Other Adverse Effects: No systematic monitoring data; responsible disposal and spill management remain essential
Waste Treatment Methods: Dispose as hazardous laboratory chemical waste per local, regional, and national environmental regulations Contaminated Packaging: Rinse thoroughly, then treat as hazardous chemical waste Measures for Safe Disposal: Incineration in approved facility, or chemical treatment following institution guidelines; avoid landfill or drain disposal Contact Authorities: Consult local environmental protection departments for clarification on legal disposal methods and record keeping
UN Number: Not classified by current transport regulations UN Proper Shipping Name: Not assigned Transport Hazard Class: None allocated Packing Group: Not established Special Precautions for User: Transport in tightly sealed, clearly labeled containers; store upright, prevent knocks or tumbles Other Information: If shipped by courier, follow all requirements for research chemical labeling and documentation
Regulations: No registration in major chemical control schedules (REACH, TSCA, etc.) found in public databases; verify up-to-date regulatory status with supplier and relevant authorities Label Elements: Clearly show hazard pictograms, statements, and supplier information (as dictated by GHS and national rules) SARA Title III (USA) Section 313: Not listed as of last survey California Proposition 65: Not listed Other Country-Specific Regulations: Users responsible for identifying obligations under their national and regional health, safety, and environmental laws
