Possibility of Hazardous Reactions: Can react violently with strong oxidizing agents
Conditions to Avoid: Prolonged exposure to heat, light and moisture, contact with open flames
Incompatible Materials: Avoid strong acids, bases, and reducing agents
Hazardous Decomposition Products: Bromine vapors, carbon monoxide, carbon dioxide, short-chain organic acids
Likely Routes of Exposure: Inhalation, skin contact, eye contact, ingestion
Acute Toxicity: Limited specific data; structurally related compounds cause skin/eye irritation and are moderately toxic on ingestion
Skin Corrosion/Irritation: Causes mild to moderate irritation, redness, possible blistering
Eye Damage/Irritation: Causes significant eye discomfort and redness
Respiratory Sensitization: Can irritate airways; high levels may cause coughing, shortness of breath
Ingestion Effects: Nausea, abdominal discomfort, vomiting if swallowed
Chronic Effects: No chronic toxicity data available; handle as a potential cumulative hazard
Carcinogenicity, Mutagenicity, Reproductive Toxicity: Not classified as carcinogen by IARC, NTP, OSHA; mutagenic/reproductive effects not studied
Symptoms of Overexposure: Burning sensation, skin inflammation, eye watering, difficulty breathing with large exposures
Ecotoxicity: Not tested in detail; brominated esters often toxic to aquatic organisms even at low levels
Persistence and Degradability: May persist in water and soil, slow biodegradation likely due to ester and bromo group stability
Bioaccumulative Potential: Potential to bioaccumulate due to lipophilicity (high log Kow)
