1-chloro-4-methylbenzene

1-chloro-4-methylbenzene is an aromatic halogenated hydrocarbon with the molecular formula C7H7Cl and CAS number 106-43-4. This organic compound consists of a benzene ring substituted with a chlorine atom and a methyl group in para positions. With a molecular weight of 126.58 g/mol, it belongs to the chlorotoluene family and is classified as a moderately hazardous substance requiring proper handling precautions.

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 dissolves readily in organic solvents such as alcohols, ethers, and hydrocarbons. The compound exhibits typical properties of chlorinated aromatics including moderate volatility and stability under normal conditions, making it suitable for various industrial applications requiring controlled solvent characteristics.

1-chloro-4-methylbenzene is primarily used as an intermediate in organic synthesis and chemical manufacturing processes. It serves as a building block for producing pharmaceuticals, agrochemicals, and specialty chemicals. The compound is also utilized in research laboratories for synthetic chemistry applications and as a solvent in specific industrial processes where its aromatic and halogenated properties are beneficial for reaction outcomes.

1-chloro-4-methylbenzene requires careful handling due to its Acute Tox. 4 classification. Always wear appropriate personal protective equipment including chemical-resistant gloves, safety goggles, and protective clothing. Ensure adequate ventilation to prevent vapor accumulation and avoid skin and eye contact. Work in well-ventilated areas or under fume hoods, and have emergency eyewash stations readily available. Follow proper hygiene practices and avoid eating, drinking, or smoking in work areas.

1-chloro-4-methylbenzene should be stored in tightly sealed containers in a cool, dry, well-ventilated area away from heat sources and direct sunlight. Keep containers upright and protected from physical damage. Store away from incompatible materials such as strong oxidizing agents and bases. Ensure storage areas have appropriate fire prevention measures and spill containment systems. Maintain storage temperatures within recommended ranges to prevent degradation.

1-chloro-4-methylbenzene exposure requires immediate action depending on the route of contact. 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 assistance while providing safety data sheet information.

1-chloro-4-methylbenzene disposal must comply with local and national hazardous waste regulations due to its environmental classification as Aquatic Chronic 2. Contact licensed hazardous waste disposal companies for proper treatment and disposal. Do not discharge into sewers, waterways, or soil. Small quantities may require specialized incineration at high temperatures with appropriate emission controls. Always consult local environmental authorities for specific disposal requirements and documentation.

1-chloro-4-methylbenzene is classified as ADR Class 3 (flammable liquids), Packing Group III for transportation purposes. It requires appropriate UN specification packaging and hazard labeling during transport. Vehicles must carry proper documentation including transport documents and emergency response information. Drivers need ADR training certification, and transport routes should avoid populated areas when possible. Ensure compliance with international dangerous goods regulations for cross-border shipments.

1-chloro-4-methylbenzene is regulated under European REACH and CLP regulations requiring proper registration, classification, and safety data sheet provision. It is not currently listed as a Substance of Very High Concern (SVHC). Companies must comply with occupational exposure limits, environmental discharge restrictions, and proper hazard communication requirements. Regular monitoring and risk assessments may be required depending on usage volumes and applications in industrial settings.
