For procurement managers and R&D scientists in the chemical industry, understanding the detailed properties and proper handling procedures for key intermediates like 2,4,6-Trichloroaniline (CAS 634-93-5) is fundamental to safe and efficient operations. This compound, while highly useful, requires careful management from procurement to application.

Key Physical and Chemical Properties

2,4,6-Trichloroaniline, with the chemical formula C6H4Cl3N and a molecular weight of 196.46 g/mol, is typically supplied as a yellow to white crystalline powder. Its melting point ranges from 73-75 °C, indicating it is a solid at room temperature. Unlike highly water-soluble compounds, its solubility in water is low (approximately 0.039 g/L at 25°C), but it dissolves readily in common organic solvents such as ethanol, diethyl ether, and carbon disulfide. This solubility profile is important for its use in various organic synthesis reactions and purification processes.

Safe Handling and Storage Recommendations

As with many chlorinated aromatic compounds, 2,4,6-Trichloroaniline presents certain hazards. It is classified as harmful if swallowed, inhaled, or in contact with skin, and can cause skin irritation. Therefore, when handling this chemical, it is imperative to adhere to strict safety protocols. Procurement professionals should ensure that suppliers provide comprehensive Safety Data Sheets (SDS). Personnel working with 2,4,6-Trichloroaniline must wear appropriate personal protective equipment (PPE), including chemical-resistant gloves, safety goggles, lab coats, and, if airborne dust is a concern, respiratory protection. Operations should be conducted in well-ventilated areas, preferably under a fume hood.

Storage conditions are also critical. Warehouses storing 2,4,6-Trichloroaniline should be well-ventilated, dry, and kept at a low temperature. Crucially, it must be stored separately from acids, strong oxidizing agents, and food additives to prevent hazardous reactions. Proper labeling and segregation of chemicals are essential for maintaining a safe working environment. For companies looking to buy this compound, understanding these handling and storage requirements from the outset is a part of responsible procurement.

Procurement Considerations: Quality and Supplier Reliability

When sourcing 2,4,6-Trichloroaniline, manufacturers and researchers should prioritize suppliers who can guarantee high purity, typically exceeding 98%. The price of the chemical can vary, but consistent quality and a stable supply chain are paramount for industrial applications. Partnering with a reputable manufacturer, particularly one with experience in exporting from China, can provide cost-effective solutions without sacrificing quality.

By thoroughly understanding the properties and safety requirements of 2,4,6-Trichloroaniline and by choosing a reliable supplier, businesses can effectively integrate this valuable intermediate into their processes, ensuring both operational safety and product excellence.
