First Aid Measures

Inhalation: Move affected person to fresh air, monitor for signs of respiratory distress, seek medical attention if symptoms persist or develop
Skin Contact: Remove contaminated clothing and shoes, wash skin thoroughly with soap and water, do not use solvents or thinners, medical attention required if irritation continues
Eye Contact: Rinse immediately under running water for at least 15 minutes, lift upper and lower eyelids, seek prompt ophthalmologic evaluation
Ingestion: Rinse mouth with water, do not induce vomiting, give small quantities of water if victim is conscious, obtain medical care, provide details on chemical for treatment guidance
Most Important Symptoms: Irritation, localized burns, airway difficulty, allergic reactions, possible delayed effects on liver and kidneys

Fire-Fighting Measures

Suitable Extinguishing Media: Use dry chemical powder, foam, or carbon dioxide; water spray recommended for larger fires/oil containment
Unsuitable Media: Avoid direct water jet which could spread solid or dust clouds containing chemical
Fire Hazards: Toxic, corrosive, and irritating gases (such as hydrogen chloride, nitrogen oxides, sulfur oxides, and hydrogen fluoride) may form during combustion
Protective Equipment: Full protective suit, self-contained breathing apparatus; keep containers cool by spraying with water if exposed to fire
Other Advice: Move unaffected materials from fire zone, avoid exposure to vapors, dike fire control water for later disposal if possible

Accidental Release Measures

Personal Precautions: Stop release at source, evacuate unnecessary personnel from affected area, ventilate, avoid creating dust or aerosol
Protective Equipment: Nitrile gloves, chemical splash goggles, lab coat, suitable vapor/powder respirator (P3/organic vapor/acid gas cartridge)
Environmental Precautions: Prevent from entering drains, watercourses, and soil, report significant spills to environmental authorities
Clean-Up Methods: Sweep or vacuum solid/spilled powder using tools resistant to corrosion, collect in suitably labeled containers, wipe area with damp cloth using appropriate solvent if safe
Disposal: Follow local regulations regarding hazardous chemical disposal; decontaminate spill area after removal

Handling and Storage

Handling: Use in fume hood or well-ventilated area, minimize dust generation, handle with nitrile or butyl gloves, do not mix with strong acids or bases; avoid contact with eyes, skin, or clothing
Storage: Keep tightly sealed in original labeled packaging, store away from incompatible materials such as strong oxidizers or reducing agents or extremes of temperature; maintain in cool, dry place out of direct sunlight. Store below 25°C
Other Guidance: Keep away from food and beverages; follow defined housekeeping procedures to avoid contamination; use only with chemical safety training

Exposure Controls and Personal Protection

Exposure Limits: No established ACGIH/TLV or OSHA PEL; minimize to lowest practical levels
Engineering Controls: Chemical fume hood or local exhaust ventilation required; eyewash and safety showers accessible in work area
Personal Protective Equipment: Splash proof chemical goggles, nitrile gloves, laboratory coat/gown, closed footwear, if risk of exposure high, certified respirator (APF ≥ 10 recommended)
Other Protection: Wash hands and exposed skin before breaks and after work, remove contaminated clothing and launder before reuse

Physical and Chemical Properties

Form: Pale yellow to yellow-brown crystalline solid or fine powder
Odor: Slight chemical odor, non-distinct
Melting Point: 155–165°C (specimen dependent)
Boiling Point: Data not available (may decompose before boiling)
Solubility: Soluble in DMSO, methanol, and acetonitrile; sparingly soluble in water
Density: Approx. 1.5 g/cm3 (estimated)
pH (aqueous suspension): Not determined, likely acidic
Vapor Pressure: Negligible at room temperature
Partition Coefficient (log Kow): No reliable data; expect moderate logP due to aromatic and cyclopropyl content
Stability Under Ordinary Conditions: Stable at room temperature, out of direct sunlight, in airtight container

Stability and Reactivity

Chemical Stability: Stable if stored out of light and moisture at recommended temperature
Reactivity: May react with strong bases, oxidizing or reducing agents, or under elevated temperature
Hazardous Decomposition Products: Hydrogen chloride, nitrogen oxides, sulfur oxides, fluorinated degradation products as toxic gases/fumes
Conditions to Avoid: Contact with incompatible materials, excessive heat, sparks, static discharge
Polymerization: No hazardous polymerization expected under normal handling

Toxicological Information

Acute Toxicity: Experimental data limited; anticipated oral LD50 in rats under 200 mg/kg (based on related structures); inhalation exposure data not established
Chronic Effects: Possible organ toxicity with repeated exposure; animal studies indicate possible liver and kidney changes at high doses
Irritation: Eye, skin, and respiratory tract irritant; possible allergic response on repeat contact
Carcinogenicity: No data available; related compounds not classified as carcinogens by IARC, NTP, or OSHA
Mutagenicity: No mutagenicity data reported; treat as mutagenic unless proven otherwise

Ecological Information

Ecotoxicity: Harmful to fish, aquatic invertebrates, and algae at concentrations below 1 mg/L; risk of bioaccumulation in some organisms
Persistence and Degradability: Poorly biodegradable; main component resists hydrolysis, some environmental breakdown under sunlight likely produces toxic fragments
Mobility in Soil: Likely to bind to soil particles, but some components may leach to groundwater due to partial water solubility
Other Adverse Effects: Long-term release can cause toxic build-up in aquatic environments; avoid uncontrolled disposal

Disposal Considerations

Waste Disposal Methods: Treat as hazardous waste; incinerate in approved chemical incinerator with afterburner and scrubber
Container Disposal: Rinse empty containers with suitable solvent and water, dispose of residues and containers as hazardous chemical waste per local guidelines
Other Instructions: Do not discharge to public wastewater or natural environment; consult local/regional regulatory authorities for authorized chemical treatment or disposal contractors
