Composition / Information on Ingredients

Chemical Name: 2-Bromopropane
CAS Number: 75-26-3
Concentration: 99% or higher in standard laboratory formulations
Impurities: Trace isomers, minor unreacted precursors depending on synthesis

First Aid Measures

Eye Contact: Rinse cautiously with water for several minutes, remove contact lenses if present, seek medical attention if symptoms persist
Skin Contact: Remove contaminated clothing, flush skin with plenty of water, wash thoroughly with soap, seek medical advice for ongoing irritation
Inhalation: Move to fresh air immediately, seek medical help if breathing is difficult or symptoms develop
Ingestion: Rinse mouth, do not induce vomiting, call emergency medical services or poison control
Advice for Medical Staff: Treat symptomatically, monitor respiratory and nervous system function, provide supportive care as needed

Fire-Fighting Measures

Suitable Extinguishing Media: Dry chemical, carbon dioxide, alcohol-resistant foam
Unsuitable Extinguishing Media: Direct water jet can spread the fire
Specific Hazards Arising from Chemical: Releases toxic fumes including hydrogen bromide, carbon oxides under combustion
Protective Equipment: Firefighters need self-contained breathing apparatus and protective clothing
Fire Fighting Instructions: Cool containers exposed to heat with water from a safe distance, use caution with runoff water to avoid environmental contamination

Accidental Release Measures

Personal Precautions: Evacuate area, ensure adequate ventilation, wear personal protective equipment
Environmental Precautions: Prevent leakage or spillage into drains, surface and groundwaters
Containment and Cleanup: Absorb with inert material such as sand or vermiculite, collect and place into proper waste containers, ventilate area, wash spill site after cleanup

Handling and Storage

Handling: Use only in well-ventilated areas, avoid breathing vapors, avoid contact with skin and eyes, handle away from ignition sources
Storage: Store in tightly closed containers, in a cool, dry, well-ventilated area, away from incompatible materials such as oxidizing agents, acids, store separately from food and beverages, label containers clearly

Exposure Controls and Personal Protection

Engineering Controls: Use fume hood or local exhaust ventilation to minimize airborne exposure
Eye Protection: Chemical safety goggles or face shield
Skin Protection: Suitable impervious gloves, lab coat, and long sleeves
Respiratory Protection: Suitable respirator if airborne exposure exceeds recommended limits
Occupational Exposure Limits: No established OSHA or ACGIH TLV for 2-bromopropane, but follow general safe practice for volatile brominated hydrocarbons

Hazardous Decomposition: Produces hydrogen bromide and carbon oxides on combustion or decomposition
Polymerization: Not known to occur under normal process conditions

Toxicological Information

Acute Effects: Harmful if inhaled, ingested, or absorbed through skin, causes skin and eye irritation, central nervous system depression possible
Chronic Effects: Prolonged or repeated exposure may affect blood, reproductive organs, and nervous system
Carcinogenicity: Classified as possibly carcinogenic, some studies in animals and limited human evidence
Mutagenicity: Positive results in some cytogenetic studies
Other Data: Rat oral LD50 = 2500 mg/kg, human case reports link high exposure with peripheral neuropathy and hematologic toxicity

Ecological Information

Ecotoxicity: Toxic to aquatic organisms at high concentrations, possible long-term adverse effects
Persistence and Degradability: Moderately persistent in the environment, slowly biodegradable
Bioaccumulaton: Potential for bioaccumulation limited by volatility and solubility
Mobility in Soil: May leach to groundwater, especially in sandy soils

Disposal Considerations

Waste Treatment: Collect and dispose as hazardous waste in accordance with local, regional, and national regulations
Methods: Incinerate under controlled conditions using licensed waste handler, do not pour down drains or release to the environment
Contaminated Packaging: Triple rinse containers, puncture and dispose as hazardous waste
