Incompatibilities: Strong acids, oxidizers, bases
Storage Temperature: Ambient (room temperature)

Exposure Controls and Personal Protection

Engineering Controls: General and local exhaust ventilation to minimize exposure
Personal Protective Equipment: Chemical-resistant gloves (nitrile or neoprene), safety goggles, lab coat or chemical apron, appropriate respiratory protection if dust present or ventilation inadequate
Occupational Exposure Limits: No data specific to compound; observe general dust threshold limits (e.g., ACGIH, OSHA standards)
Environmental Controls: Avoid release to environment, provide spill containment

Toxicological Information

Likely Routes of Exposure: Inhalation, skin contact, eye contact, ingestion
Acute Toxicity: Oral LD50 (rat) estimated 500-2000 mg/kg (based on structural analogs); low to moderate hazard
Skin/Eye Irritation: May cause irritation, redness, burning, watering of eyes
Chronic Effects: Prolonged exposure may affect liver, kidneys (based on related compounds)
Carcinogenicity/Mutagenicity: No information specific to compound; cresol derivatives not generally classified as carcinogenic
Sensitization: Not expected based on available data

Ecological Information

Ecotoxicity: Harmful to aquatic life based on analogy to sulfonic acid salts and cresol derivatives
Degradability: Partially biodegradable; sulfonic acids tend to persist in environment, ammonia content may contribute to nutrient loading in water bodies
Mobility in Soil: High water solubility increases potential for mobility and leaching
Bioaccumulation: Unlikely to bioaccumulate significantly
Further Information: Avoid contamination of surface waters, groundwater, and soil; follow local regulations for discharge limits

Disposal Considerations

Disposal Methods: Dispose in accordance with local, regional, national, and international regulations through licensed chemical waste disposal contractor
Container Disposal: Triple rinse container, puncture and render unusable, dispose as hazardous chemical waste
Precautions: Do not allow undiluted product or large quantities to reach sewage systems
Waste Code: Consult local regulatory requirements for hazardous waste codes (possible hazardous waste depending on concentration and local rules)
