1-chloro-4-methylbenzene

1-chloro-4-methylbenzene is an aromatic organochlorine compound with the molecular formula C7H7Cl and CAS number 106-43-4. This substance consists of a benzene ring substituted with a chlorine atom and a methyl group in para position. With a molecular weight of 126.58 g/mol, it belongs to the family of chlorotoluenes and is classified as moderately hazardous to health and aquatic environments.

1-chloro-4-methylbenzene is a colorless to pale yellow liquid at room temperature with a characteristic aromatic odor. It has low water solubility but is readily soluble in organic solvents such as alcohols, ethers, and hydrocarbons. The compound has a boiling point around 162°C and a density of approximately 1.07 g/cm³. It is stable under normal conditions but can be volatile.

1-chloro-4-methylbenzene serves primarily as an intermediate in organic synthesis and pharmaceutical manufacturing. It is used in the production of dyes, agrochemicals, and specialty chemicals. The compound also finds applications in the synthesis of various aromatic compounds and as a solvent in specific industrial processes. Its reactivity makes it valuable for nucleophilic substitution reactions and other chemical transformations.

Safe handling of 1-chloro-4-methylbenzene requires 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 prevent inhalation exposure. Avoid skin and eye contact, and ensure no ignition sources are present due to its flammable nature. Always follow established safety protocols and maintain emergency equipment nearby.

1-chloro-4-methylbenzene should be stored in a cool, dry, well-ventilated area away from heat sources, sparks, and open flames. Keep containers tightly sealed and upright in a designated chemical storage area. Avoid storage near incompatible materials such as strong oxidizing agents and bases. Ensure proper labeling according to GHS requirements and maintain appropriate spill containment measures in the storage area.

In case of skin contact with 1-chloro-4-methylbenzene, immediately remove contaminated clothing and wash the affected area thoroughly with soap and water for at least 15 minutes. If eye contact occurs, flush eyes with clean water for 15 minutes while holding eyelids open. In case of inhalation, move to fresh air immediately. Seek medical attention if symptoms persist or for significant exposures.

Disposal of 1-chloro-4-methylbenzene must comply with local, national, and EU waste regulations. The substance should be treated as hazardous waste and disposed of through licensed waste management companies. Never discharge into drains, soil, or water bodies due to its aquatic toxicity classification. Incineration at authorized high-temperature facilities is typically the preferred disposal method for organic chlorinated compounds.

1-chloro-4-methylbenzene is classified under ADR transport regulations as Class 3 (flammable liquids), Packing Group III. Transportation requires appropriate packaging, labeling, and documentation according to dangerous goods regulations. Vehicles must display proper placards and carry safety equipment. Only trained personnel should handle the transport, and emergency response information must be readily available during shipment.

1-chloro-4-methylbenzene is regulated under EU REACH and CLP regulations, requiring registration and proper classification. It carries GHS pictograms GHS07 and GHS09 with 'Warning' signal word, indicating moderate acute toxicity and aquatic hazard. The substance is not currently listed as SVHC (Substance of Very High Concern) but users must comply with safety data sheet requirements and exposure limits.
