2,3,4-trichlorobut-1-ene

2,3,4-trichlorobut-1-ene is an organochlorine compound with the molecular formula C4H5Cl3 and CAS number 2431-50-7. This chemical substance has a molecular weight of 159.44 g/mol and belongs to the family of chlorinated alkenes. It is classified as a hazardous substance with multiple danger categories including carcinogenic properties (Category 2), acute toxicity, and environmental hazards. The compound requires careful handling due to its significant health and safety risks.

2,3,4-trichlorobut-1-ene is a chlorinated organic compound that typically exists as a liquid at room temperature. As a halogenated alkene, it exhibits limited water solubility due to its hydrophobic nature and the presence of three chlorine atoms. The compound's physical properties are influenced by the electron-withdrawing chlorine substituents, which affect its volatility, boiling point, and chemical reactivity. Specific physical constants should be confirmed through technical data sheets for precise applications.

2,3,4-trichlorobut-1-ene is primarily used as a chemical intermediate in organic synthesis and industrial chemical processes. Its applications typically involve use as a building block for the synthesis of other chlorinated compounds or as a reagent in specialized chemical reactions. Due to its hazardous classification, including carcinogenic properties, its use is restricted to professional industrial settings with appropriate safety controls and regulatory compliance measures in place.

2,3,4-trichlorobut-1-ene must be handled with extreme caution using appropriate personal protective equipment including chemical-resistant gloves, safety goggles, and respiratory protection. Work should be conducted in well-ventilated areas or under fume hoods to prevent inhalation exposure. Given its carcinogenic classification (Category 2) and acute toxicity, minimize skin and eye contact, avoid vapor inhalation, and ensure proper training for all personnel handling this substance.

2,3,4-trichlorobut-1-ene should be stored in tightly sealed, chemically compatible containers in a cool, dry, well-ventilated area away from heat sources and direct sunlight. Storage areas must be equipped with appropriate containment measures and emergency equipment. Keep away from incompatible materials such as strong oxidizers, bases, and reactive metals. Ensure storage complies with local regulations for hazardous chemicals and maintain proper inventory management for carcinogenic substances.

Immediate action is required in case of contact with 2,3,4-trichlorobut-1-ene. For skin contact, remove contaminated clothing and wash thoroughly with soap and water for at least 15 minutes. In case of eye contact, flush immediately with clean water for at least 15 minutes and seek medical attention. If inhaled, move to fresh air immediately. For ingestion, do not induce vomiting and seek immediate medical attention. Always consult a physician and provide the safety data sheet.

2,3,4-trichlorobut-1-ene must be disposed of as hazardous waste through licensed waste management companies specializing in dangerous chemicals. Due to its carcinogenic classification and environmental hazard rating (Aquatic Acute 1), it cannot be disposed of through regular waste streams or released into the environment. Disposal must comply with local, national, and EU waste regulations. Containers should be properly labeled and segregated according to waste classification requirements.

2,3,4-trichlorobut-1-ene is classified under ADR Class 6.1 (Toxic substances), Packing Group II, indicating significant transport hazards. Transportation must comply with ADR regulations for dangerous goods, requiring appropriate packaging, labeling with GHS pictograms (GHS08, GHS06, GHS09), and proper documentation. Vehicles must carry emergency equipment, and drivers need ADR certification. Shipments require hazard placarding and adherence to routing restrictions for toxic materials.

2,3,4-trichlorobut-1-ene is subject to extensive EU chemical regulations including REACH registration requirements and CLP classification obligations. Its carcinogenic classification (Category 2) triggers additional workplace safety regulations and potential use restrictions. While not currently listed as an SVHC, it requires compliance with occupational exposure limits and may be subject to authorization procedures. Users must ensure proper risk assessments, safety data sheet provision, and regulatory notification requirements are met.
