Hexadecyl 3-amino-4-chlorobenzoate

Hexadecyl 3-amino-4-chlorobenzoate is an organic chemical compound with the molecular formula C23H38ClNO2 and CAS number 143269-74-3. This substance is an ester derivative of benzoic acid featuring a long hexadecyl chain, an amino group, and a chlorine substituent on the benzene ring. With a molecular weight of 396 g/mol, it belongs to the class of substituted benzoate esters and is classified as having chronic aquatic toxicity properties under GHS classification system.

Hexadecyl 3-amino-4-chlorobenzoate is typically a solid compound at room temperature due to its long aliphatic chain structure. The presence of the hexadecyl group suggests limited water solubility but good solubility in organic solvents. The compound's physical appearance, exact melting point, and specific solubility data would require analytical characterization. The molecular structure combining aromatic and long-chain aliphatic components indicates amphiphilic properties, making it potentially useful in surfactant or emulsification applications.

Hexadecyl 3-amino-4-chlorobenzoate is primarily used in specialized chemical applications where its unique structural properties are beneficial. The compound's combination of aromatic functionality and long alkyl chain makes it suitable for surfactant formulations, emulsification processes, and potential pharmaceutical intermediates. It may also serve as a building block in organic synthesis or as a functional additive in materials science applications. The amino and chloro substituents provide reactive sites for further chemical modifications in research and development contexts.

Hexadecyl 3-amino-4-chlorobenzoate should be handled with standard laboratory safety precautions including wearing appropriate personal protective equipment such as safety glasses, gloves, and lab coats. Work in well-ventilated areas or under fume hoods to minimize exposure. While the compound doesn't carry acute hazard pictograms, its chronic aquatic toxicity classification (Aquatic Chronic 2) requires careful handling to prevent environmental release. Avoid direct skin and eye contact, and ensure proper hygiene practices including thorough handwashing after handling.

Hexadecyl 3-amino-4-chlorobenzoate should be stored in a cool, dry place away from direct sunlight and heat sources. Keep containers tightly sealed to prevent moisture absorption and contamination. Store separately from strong oxidizing agents, acids, and bases that could react with the amino or ester functional groups. Maintain storage temperatures below 25°C when possible and ensure adequate ventilation in storage areas. Label containers clearly with substance name, hazard information, and storage date for proper inventory management and safety compliance.

In case of skin contact with hexadecyl 3-amino-4-chlorobenzoate, immediately remove contaminated clothing and wash the affected area thoroughly with soap and water for at least 15 minutes. For eye contact, rinse immediately with clean water for 15-20 minutes while holding eyelids open. If inhaled, move the person to fresh air and monitor breathing. If swallowed, do not induce vomiting and seek medical attention. In all cases of significant exposure or if symptoms develop, consult a physician and provide the safety data sheet.

Hexadecyl 3-amino-4-chlorobenzoate must be disposed of through licensed chemical waste disposal services due to its Aquatic Chronic 2 classification. Never discharge this substance into sewers, waterways, or soil as it poses environmental hazards. Collect waste in appropriate containers, clearly labeled with contents and hazard information. Contact certified waste management companies that specialize in chemical disposal and can ensure proper treatment or incineration. Follow local and EU regulations regarding hazardous waste documentation and tracking throughout the disposal process.

Hexadecyl 3-amino-4-chlorobenzoate is classified under ADR Class 9 (Miscellaneous dangerous goods), Packing Group III, indicating it requires regulated transport procedures. Use appropriate packaging that meets UN specification requirements for Class 9 materials. Ensure proper labeling with GHS09 environmental pictogram and relevant transport documentation. Vehicles must carry appropriate emergency response information and drivers should be trained in hazardous materials transport. Follow ADR regulations for loading, segregation from incompatible materials, and emergency response procedures during transportation.

Hexadecyl 3-amino-4-chlorobenzoate is subject to EU REACH regulation requiring registration for commercial use and CLP regulation for classification and labeling as Aquatic Chronic 2. The substance is not currently listed as a Substance of Very High Concern (SVHC). Users must comply with safety data sheet requirements, worker protection measures, and environmental release prevention. Industrial users should verify registration status and any use restrictions. Transport requires compliance with ADR Class 9 regulations, and disposal must follow hazardous waste management directives.
