1,2-dibromoethane

1,2-dibromoethane is an organobromine compound with the molecular formula C2H4Br2 and CAS number 106-93-4. This chemical substance has a molecular weight of 187.86 g/mol and belongs to the family of dibromoalkanes. It is classified as a highly hazardous substance with carcinogenic properties (Carc. 1B) and acute toxicity (Acute Tox. 3). The compound requires careful handling due to its significant health risks and environmental concerns.

1,2-dibromoethane is a colorless liquid with a sweet, chloroform-like odor at room temperature. It has a high density and is slightly soluble in water but miscible with most organic solvents including alcohols and ethers. The compound has a relatively low boiling point and high vapor pressure, making it volatile. Its chemical structure consists of two carbon atoms each bonded to a bromine atom, creating a symmetrical dibromoalkane molecule.

1,2-dibromoethane is primarily used as an intermediate in chemical synthesis and as a solvent in specialized industrial applications. It serves as a fumigant for soil treatment and grain storage, though this use has been largely restricted due to health concerns. The compound is also utilized in the production of other brominated chemicals and as a scavenging agent in leaded gasoline formulations, although environmental regulations have limited many of these applications.

1,2-dibromoethane requires strict safety protocols including wearing appropriate personal protective equipment such as chemical-resistant gloves, safety goggles, and respiratory protection. Work must be conducted in well-ventilated areas or under fume hoods to prevent inhalation exposure. Due to its carcinogenic classification (Carc. 1B) and acute toxicity, minimize skin contact and vapor inhalation. Ensure emergency washing facilities are readily available and follow established chemical hygiene procedures at all times.

1,2-dibromoethane must be stored in tightly sealed containers in a cool, dry, well-ventilated area away from heat sources and direct sunlight. Keep containers away from incompatible materials such as strong oxidizers and alkali metals. Storage areas should be equipped with appropriate spill containment measures and emergency equipment. Due to its volatile nature and toxicity, storage should comply with local regulations for hazardous substances and be limited to authorized personnel only.

1,2-dibromoethane exposure requires immediate action: for skin contact, remove contaminated clothing and wash affected area thoroughly with soap and water for at least 15 minutes. In case of eye contact, flush immediately with clean water for 15 minutes while holding eyelids open. If inhaled, move to fresh air immediately and seek medical attention. For ingestion, do not induce vomiting and seek immediate medical care. Always consult a physician after any exposure incident.

1,2-dibromoethane disposal must comply with local and international hazardous waste regulations due to its toxic and carcinogenic properties. The substance cannot be disposed of in regular waste streams and requires treatment by licensed hazardous waste disposal companies. Incineration at high temperatures in specialized facilities is typically the preferred disposal method. Always consult with environmental authorities and waste management professionals to ensure proper disposal procedures and documentation are followed.

1,2-dibromoethane is classified under ADR as Class 6.1 (toxic substances) with Packing Group I, indicating high toxicity. Transportation requires proper hazardous goods packaging, labeling with appropriate GHS pictogrammes (GHS08, GHS06, GHS09), and accompanying safety documentation. Vehicles must carry emergency response information and drivers need hazardous materials certification. Shipments must comply with international dangerous goods regulations and use authorized transport companies experienced in handling toxic chemicals.

1,2-dibromoethane is subject to extensive regulatory oversight under REACH, CLP, and other chemical safety frameworks due to its carcinogenic classification and environmental concerns. The substance requires registration, authorization procedures, and strict compliance with occupational exposure limits. Many countries have implemented restrictions or bans on certain uses, particularly as a fumigant. Companies handling this chemical must maintain detailed safety data sheets, implement risk management measures, and ensure regulatory compliance.

1,2-dibromoethane is available through specialized chemical distributors in Europe, including OYSI, which supplies high-quality chemical products to industrial customers across the European market. Due to its hazardous classification and regulatory restrictions, purchase requires proper authorization, compliance documentation, and adherence to safety protocols. Buyers must demonstrate legitimate industrial use and appropriate handling capabilities.
