Name: 1-Bromo-2,2-dimethylpropane
Chemical Formula: C5H11Br
Description: A colorless to pale yellow liquid with a pungent odor used in research and some organic synthesis processes. Its identity stands clear in labs where strict labeling means fewer mix-ups or unnecessary risks.
Type of Hazard: Flammable liquid and vapor, toxicity to skin and eyes, respiratory tract irritation, possible central nervous system effects on heavy exposure
Hazard Symbols: GHS02 (Flame), GHS07 (Exclamation mark)
Precautionary Statements: Avoid inhalation and contact with skin or eyes. Keep away from heat sources, sparks, open flames, or anything that can start a fire. Good ventilation reduces risk.
Main Component: 1-Bromo-2,2-dimethylpropane at concentrations near 100% in pure form. Mixtures are rare in most uses, but trace impurities could exist as a result of manufacturing byproducts or degradation products.
Inhalation: Remove exposed individual from area to fresh air, watch for difficulty breathing, and support breathing as necessary. Breathing in fumes can irritate the airways quickly, so rapid action makes a difference.
Skin Contact: Wash thoroughly with soap and plenty of water. Remove any clothing that’s been doused to keep the stuff from staying too long in contact with skin.
Eye Contact: Rinse cautiously with water for several minutes, opening eyelids fully to flush out the chemical.
Ingestion: Do not induce vomiting. Sip water if conscious. Medical assistance should follow, because just a little bit through the mouth can upset the digestive tract.
Suitable Extinguishing Media: Use foam, carbon dioxide, or dry chemical powder. Water spray can work on small fires, but it can spread contamination if used improperly.
Specific Hazards Arising from Chemical: Gives off toxic gases (mainly hydrogen bromide and possibly carbon monoxide) when burned. Vapors may form explosive mixtures with air.
Protective Equipment for Firefighters: Positive pressure self-contained breathing apparatus and full protective clothing. The fumes can damage lungs or eyes even beyond the reach of the flames.
Personal Precautions: Use personal protective equipment: gloves, goggles, lab coats. Avoid breathing vapors and ensure proper ventilation.
Containment and Clean-Up: Absorb spills with inert material such as sand or vermiculite. Collect in containers for proper disposal. Ventilate any affected area to disperse vapors. Don’t let materials soak into drains or water bodies.
Handling: Work in a chemical fume hood or well-ventilated area to minimize inhalation risks. Wear gloves and goggles to keep skin and eyes safe.
Storage: Keep in tightly closed containers. Store away from ignition sources, oxidizing substances, acids, and out of direct sunlight. A cool, dry place extends the shelf-life and keeps accidental exposures to a minimum.
Occupational Exposure Limits: Not officially established, but general solvent limits apply. Lower exposure is always safer.
Engineering Controls: Use mechanical exhaust or local ventilation to avoid exposure to vapors.
Personal Protective Equipment: Nitrile gloves, splash goggles, flame-retardant clothing, and in high vapor concentrations, use of appropriate respirator. Washing hands after handling keeps contamination from spreading to surfaces or food.
Appearance: Colorless to pale yellow liquid
Odor: Strong, biting, sweet odor
Melting Point: Near -70°C
Boiling Point: Around 90–95°C
Flash Point: Close to 14°C (closed cup, based on comparable compounds)
Solubility: Practically insoluble in water; mixes with most organic solvents
Vapor Pressure: Moderate at room temperature
Density: Heavier than water
Chemical Stability: Stable under normal temperatures and pressures as long as it’s sealed up and away from incompatible substances.
Conditions to Avoid: Sparks, open flames, strong oxidative conditions.
Incompatible Materials: Strong oxidizers, bases, acids.
Hazardous Decomposition Products: Burning or decomposition releases hydrogen bromide, carbon oxides, and other noxious fumes.
Routes of Exposure: Skin, eyes, inhalation, ingestion.
Acute Effects: Can irritate eyes, skin, and respiratory tract. High exposure leads to dizziness, headaches, and, in rare cases, unconsciousness.
Chronic Effects: Frequent or repeated contact may dry and crack the skin. No conclusive evidence of carcinogenicity in available literature, but long-term effects get more likely when hygiene is ignored.
Sensitization: No reported allergic reactions, but any strong chemical can prime a person for sensitivity.
Toxicity to Aquatic Life: Toxic to aquatic organisms, likely to cause long-term effects in water bodies.
Persistence and Degradability: Breaks down slowly in the environment. Incomplete removal leads to accumulation over time.
Mobility in Soil: Low, may adsorb to soil rather than move to groundwater, but contamination runs a risk.
Bioaccumulation: Expected to bioaccumulate within aquatic species because of its stability and low water solubility.
Methods of Disposal: Chemical waste incineration under strictly regulated conditions. Government-certified contractors handle collection and removal in most regulated workplaces.
Precautions: Do not pour down drains or mix with household waste. Contaminated containers and absorbents require specialized handling to make sure local waterways stay clean.
UN Number: Classified as a hazardous material for transport by most national and international agencies.
Transport Hazard Class: Flammable liquid.
Packing Group: Usually Group II, indicating moderate risk. Secure and upright containers, with clear hazard labeling, go a long way in making sure nobody gets hurt during routine transit.
Environmental Hazards: Marked as dangerous for the environment.
GHS Classification: Meets definitions for flammability, irritation, and environmental hazard categories.
Regulations: Covered by OSHA’s Hazard Communication Standard and falls under strict EPA oversight regarding disposal and emissions.
Workplace Controls: Workers should follow routine chemical hygiene plans and local chemical use policies that demand regular training and stocking up-to-date information in the lab.
