1,2,4-trichlorobenzene

1,2,4-trichlorobenzene is an organochlorine compound with the molecular formula C6H3Cl3 and CAS number 120-82-1. It belongs to the family of chlorinated benzenes, featuring three chlorine atoms attached to a benzene ring at positions 1, 2, and 4. With a molecular weight of 181.4 g/mol, this chemical compound is classified as hazardous with acute toxicity and environmental concerns, requiring careful handling in industrial applications.

1,2,4-trichlorobenzene is a colorless to pale yellow liquid at room temperature with a characteristic aromatic odor. It has limited solubility in water but dissolves readily in organic solvents such as alcohol, ether, and benzene. The compound exhibits stability under normal conditions but may decompose when heated, releasing toxic chlorinated compounds. Its chlorinated aromatic structure gives it enhanced chemical resistance compared to unsubstituted benzene derivatives.

1,2,4-trichlorobenzene serves primarily as an industrial solvent and chemical intermediate in manufacturing processes. It is commonly used in the production of pesticides, dyes, and other chlorinated organic compounds. The substance also finds application as a process solvent in chemical synthesis and as a heat transfer medium in certain industrial operations. Its stability and solvent properties make it valuable in specialized chemical manufacturing applications.

1,2,4-trichlorobenzene requires careful handling due to its Acute Tox. 4 and Skin Irrit. 2 classifications. Workers must wear appropriate personal protective equipment including chemical-resistant gloves, safety goggles, and protective clothing to prevent skin contact. Ensure adequate ventilation to minimize inhalation exposure and use the substance only in well-ventilated areas or fume hoods. Avoid contact with eyes and skin, and wash hands thoroughly after handling.

1,2,4-trichlorobenzene should be stored in tightly sealed containers in a cool, dry, well-ventilated area away from heat sources and direct sunlight. Keep containers in a designated chemical storage area with appropriate secondary containment to prevent environmental release. Store away from incompatible materials such as strong oxidizing agents and bases. Ensure storage areas are equipped with appropriate spill containment measures and emergency response equipment due to its environmental hazard classification.

In case of skin contact with 1,2,4-trichlorobenzene, immediately remove contaminated clothing and wash the affected area thoroughly with soap and water for at least 15 minutes. For eye contact, flush with clean water for at least 15 minutes and seek medical attention. If inhaled, move the person to fresh air immediately. If swallowed, do not induce vomiting and seek immediate medical attention. Always consult a physician if symptoms develop or persist after exposure.

1,2,4-trichlorobenzene must be disposed of as hazardous waste through licensed waste management companies due to its environmental hazard classification (Aquatic Acute 1; Aquatic Chronic 1). Do not discharge to sewers, waterways, or soil. Contaminated containers and materials require proper hazardous waste disposal. Follow local and national environmental regulations for chlorinated organic waste disposal. Consult with certified waste disposal specialists to ensure compliance with all applicable waste management requirements.

1,2,4-trichlorobenzene is classified as ADR Class 6.1 (Toxic substances), Packing Group III for transportation purposes. It must be packaged in UN-approved containers with appropriate hazard labels and documentation. Transport vehicles require proper placarding and emergency response information. Drivers must hold valid dangerous goods training certificates. Ensure compliance with ADR regulations for loading, segregation, and route restrictions when transporting this toxic substance across European borders.

1,2,4-trichlorobenzene is subject to REACH registration requirements and CLP classification regulations in Europe, displaying GHS07 and GHS09 pictograms with 'Warning' signal word. While not currently listed as an SVHC (Substance of Very High Concern), it requires compliance with chemical safety assessments and exposure scenarios. Users must follow occupational exposure limits and environmental discharge restrictions. Check national chemical inventories and workplace safety regulations for additional requirements in specific European countries.
