4-chloro-3-methylphenol

4-chloro-3-methylphenol is an organochlorine compound with the molecular formula C7H7ClO and CAS number 59-50-7. This chemical substance belongs to the phenol family and features both chlorine and methyl substituents on the benzene ring. With a molecular weight of 142.58 g/mol, it is classified as a hazardous substance requiring careful handling due to its toxic, corrosive, and sensitizing properties.

4-chloro-3-methylphenol is typically a solid crystalline substance at room temperature with a characteristic phenolic odor. As a phenolic compound, it exhibits moderate solubility in water and good solubility in organic solvents such as alcohols and ethers. The presence of both chlorine and methyl groups affects its volatility and stability compared to unsubstituted phenol.

4-chloro-3-methylphenol is primarily used as an intermediate in the synthesis of pharmaceuticals, pesticides, and other organic chemicals. It serves as a building block in the production of antimicrobial agents and preservatives. The compound is also utilized in research and development applications within the chemical industry for creating specialized chemical products and formulations.

4-chloro-3-methylphenol requires strict safety measures including wearing appropriate personal protective equipment: chemical-resistant gloves, safety goggles, and protective clothing. Work in well-ventilated areas or under fume hoods to avoid inhalation. Due to its corrosive nature (Skin Corr. 1C) and sensitizing properties (Skin Sens. 1B), prevent all skin and eye contact. Ensure emergency shower and eyewash stations are accessible.

4-chloro-3-methylphenol should be stored in tightly sealed containers in a cool, dry, well-ventilated area away from heat sources and direct sunlight. Keep containers in secondary containment to prevent spills. Store separately from incompatible materials such as strong oxidizers and bases. Ensure storage areas are equipped with appropriate spill control measures and maintain proper inventory records.

Skin contact with 4-chloro-3-methylphenol requires immediate removal of contaminated clothing and thorough washing with soap and water for at least 15 minutes. For eye contact, flush immediately with clean water for 15 minutes and seek medical attention. If inhaled, move to fresh air immediately. In case of ingestion, do not induce vomiting and seek immediate medical attention. Contact poison control if necessary.

4-chloro-3-methylphenol must be disposed of as hazardous waste through licensed waste management companies in accordance with local and European regulations. Due to its aquatic toxicity classification (Aquatic Acute 1), prevent environmental release. Contaminated packaging should also be treated as hazardous waste. Never dispose of this substance down drains or in regular waste streams.

4-chloro-3-methylphenol is classified under ADR as Class 6.1 (toxic substances), Packing Group II, requiring specialized packaging and documentation for transport. Shipments must comply with dangerous goods regulations including proper labeling with GHS pictogrammes (GHS05, GHS07, GHS09) and hazard warnings. Only authorized carriers experienced in handling toxic chemicals should transport this substance.

4-chloro-3-methylphenol is subject to REACH registration requirements and CLP classification regulations in Europe. While not currently listed as an SVHC (Substance of Very High Concern), it requires safety data sheets and proper hazard communication due to its multiple hazard classifications including acute toxicity, skin corrosion, and environmental hazards. Compliance with occupational exposure limits may apply.
