Tetrabromomethane

Tetrabromomethane is a halogenated organic compound with the chemical formula CBr4, consisting of a carbon atom bonded to four bromine atoms. This colorless crystalline solid has a molecular weight of 331.63 g/mol and is also known as carbon tetrabromide. It belongs to the family of tetrahalomethanes and serves as an important chemical intermediate in various industrial processes.

Tetrabromomethane is a colorless to pale yellow crystalline solid at room temperature with a characteristic sweet odor. It has a high density due to the presence of four bromine atoms and exhibits low solubility in water but dissolves well in organic solvents like chloroform and benzene. The compound sublimes readily and has a relatively low melting point around 90°C.

Tetrabromomethane is primarily used as a chemical intermediate in organic synthesis and as a source of bromine in various chemical reactions. It serves as a reagent in laboratory applications, particularly in analytical chemistry and research. The compound is also utilized in specialized industrial processes where controlled bromine release is required, though its applications are more limited compared to other halogenated compounds.

Tetrabromomethane should be handled with appropriate personal protective equipment including chemical-resistant gloves, safety goggles, and protective clothing. Work should be conducted in well-ventilated areas or under fume hoods to avoid inhalation of vapors. Although not classified under standard GHS pictograms, the compound requires careful handling due to its bromine content and potential toxicity, following standard laboratory safety protocols.

Tetrabromomethane should be stored in a cool, dry place away from direct sunlight in tightly sealed containers to prevent sublimation and contamination. The storage area must be well-ventilated and the compound should be kept away from incompatible materials such as strong bases and reducing agents. Temperature control is important to maintain the solid state and prevent vapor formation.

In case of skin contact with tetrabromomethane, immediately remove contaminated clothing and wash the affected area thoroughly with soap and water for at least 15 minutes. If inhaled, move to fresh air immediately and seek medical attention if respiratory irritation occurs. For eye contact, flush with clean water for at least 15 minutes and consult a physician if irritation persists.

Tetrabromomethane must be disposed of as hazardous chemical waste through authorized waste management companies specializing in halogenated compounds. The material cannot be disposed of in regular waste streams due to its bromine content and potential environmental impact. Collection, transport, and treatment must comply with local and European waste regulations including proper documentation and manifest requirements.

Tetrabromomethane is classified under ADR as Class 6.1 (Toxic substances), Packing Group III, requiring specific packaging and labeling for transport. Shipments must use UN-approved packaging with appropriate hazard labels and documentation. Transport vehicles must comply with ADR regulations for toxic substances, including proper placarding, driver certification, and emergency response information during transit across European borders.

Tetrabromomethane is subject to standard European chemical regulations under REACH and CLP, requiring registration and classification data from suppliers. While not currently listed as an SVHC (Substance of Very High Concern), it must comply with standard chemical safety requirements including proper labeling, safety data sheets, and exposure assessments for professional use within the European market.
