Overview
Bromoethane, commonly known as ethyl bromide, is a halogenated hydrocarbon with the chemical formula C2H5Br. It is a colorless to pale yellow liquid with a sweet, ethereal odor. The compound is highly volatile and flammable, making it essential to handle with care. Bromoethane is primarily used in organic synthesis as an ethylating agent. Its ability to introduce ethyl groups into molecules makes it valuable in the production of pharmaceuticals, agrochemicals, and other fine chemicals. Despite its utility, bromoethane is regulated due to its toxicity and environmental impact.
Physical and Chemical Properties
Bromoethane has a molecular weight of 108.97 g/mol and a density of 1.46 g/cm³ at 20°C. It boils at 38.4°C and melts at -119°C, indicating its high volatility. The liquid is slightly soluble in water but mixes well with most organic solvents like ethanol and ether. Chemically, bromoethane is reactive, particularly with strong oxidizers, and can decompose under heat to produce toxic fumes. Its volatility and flammability necessitate careful storage and handling to prevent accidents.
Main Applications
Bromoethane is widely used in organic synthesis to introduce ethyl groups into other compounds. This property is exploited in the pharmaceutical industry to manufacture drugs and intermediates. It also serves as a solvent in certain chemical processes and as a refrigerant in specialized applications. In agriculture, bromoethane was historically used as a fumigant, though its use has declined due to environmental and health concerns. Today, its applications are more controlled, focusing on laboratory and industrial synthesis where alternatives are less effective.
Safety and Storage
Bromoethane is toxic if inhaled or ingested and can cause severe irritation to the skin and eyes. Proper personal protective equipment (PPE), including gloves and goggles, is essential when handling this chemical. Adequate ventilation is required to prevent the buildup of vapors. Storage should be in a cool, dry, well-ventilated area away from heat sources and open flames. Containers must be tightly sealed to prevent evaporation and contamination. Spills should be managed using appropriate absorbents and disposed of according to local regulations.
B2B Procurement Guide
When procuring bromoethane, B2B buyers should prioritize suppliers who comply with international safety and quality standards. Verify the CAS number (74-96-4) to ensure the correct chemical is being purchased. Pricing varies based on purity and quantity, with bulk purchases typically offering cost savings. Buyers should also consider the logistics of handling and transporting this volatile chemical. Ensure that the supplier provides proper packaging and safety data sheets (SDS) to comply with regulatory requirements. Long-term storage should be minimized due to bromoethane's reactivity and shelf-life considerations.
