Suitable Extinguishing Media: Water spray, alcohol-resistant foam, dry chemical, carbon dioxide
Unsuitable Media: Direct water jet if used on large chemical fires
Fire Hazards: Product may emit toxic fumes of carbon oxides, nitrogen oxides upon combustion.
Protective Equipment for Firefighters: Wear self-contained breathing apparatus and full protective gear.
Special Procedures: Move containers from fire if safe; prevent firewater from entering drains.
Combustion Byproducts: Carbon monoxide, carbon dioxide, nitrogen oxides, low molecular weight organics.
Personal Precautions: Wear chemical-resistant gloves, safety goggles, lab coat or protective coveralls. Avoid dust generation.
Environmental Precautions: Prevent material from reaching soil, waterways, and drains.
Spill Cleanup: Contain spill, scoop dry material into a suitable container for disposal. Clean area thoroughly with water and detergent. Provide adequate ventilation.
Decontamination: Dispose contaminated materials as hazardous waste. Ventilate for airborne exposure risks.
Handling: Work inside chemical fume hood. Prevent exposure by minimizing dust, avoid ingestion and inhalation. Use dedicated tools and avoid cross-contamination with other chemicals.
Storage: Store in a tightly closed, air-tight container in a cool, dry well-ventilated place away from incompatible substances such as strong bases, water, or oxidizing agents.
Special Storage Advice: Protect from moisture and direct sunlight. Use desiccant if necessary. Clearly label all containers.
Incompatibilities: Water, strong bases, oxidizers may lead to decomposition and hazardous reactions.
Storage Temperature Range: 2–8°C recommended.
Engineering Controls: Work in a certified chemical fume hood. Use local exhaust ventilation to limit exposure.

Chemical Stability: Stable under recommended storage conditions if moisture and heat are controlled.
Reactivity: Undergoes hydrolysis with water and aqueous solutions, especially under basic conditions.
Hazardous Reactions: Decomposition with strong acids, bases, and oxidizers yields hazardous gases.
Decomposition Products: Succinimide derivatives, carbon dioxide, carbon monoxide, nitrogen oxides.
Conditions to Avoid: Exposure to moisture, high humidity, incompatible materials, or elevated temperatures can cause rapid decomposition.
Likely Routes of Exposure: Inhalation, skin and eye contact, ingestion
Acute Toxicity: Data limited; animal studies show low to moderate toxicity
Skin Corrosion/Irritation: May cause redness, dryness, or itching upon contact
Eye Damage/Irritation: Causes temporary but significant eye irritation, watering, redness
Respiratory Sensitization: Repeated inhalation may induce irritation, coughing, discomfort
Carcinogenicity: Not classified as carcinogenic by NTP, IARC, OSHA
Mutagenicity/Teratogenicity: No data indicating mutagenic or reproductive hazards
Other Effects: Prolonged exposure may cause mild reversible systemic effects, based on analogs.
Ecotoxicity: No detailed studies; expected to pose low to moderate hazard due to hydrolysis into succinimide
Persistence and Degradability: Expected to hydrolyze and degrade in aqueous environments
Bioaccumulation Potential: Low, based on rapid hydrolysis and poor lipid solubility
