4-Bromobenzoic acid is an important halogenated aromatic intermediate widely used in fine chemical and pharmaceutical industries. It can conduct various substitution, coupling and esterification reactions to synthesize diversified organic derivatives. It acts as core raw material for manufacturing antibacterial, anti-inflammatory and antitumor drugs, contributing to molecular structure optimization of active pharmaceutical ingredients. In agrochemical field, it is applied to prepare high-efficiency pesticides and plant growth regulators. Besides, it serves as modifier for synthetic dyes, resin materials and chemical analytical reagents. Its stable chemical structure and active reaction property make it indispensable in new drug development, pesticide synthesis and organic material preparation.

This chemical has moderate irritation and certain harm risk. Inhalation of fine powder may cause respiratory tract discomfort, perform operations in ventilated space and wear protective mask. Direct skin contact easily leads to redness and itching, wear anti-corrosion gloves and clean skin timely after exposure. Eye contact will cause severe stinging pain, continuously flush eyes with running water for over fifteen minutes. Accidental intake may damage digestive system. Thermal decomposition produces toxic bromide fume. Keep away from high temperature, open flame and strong oxidizing substances. Do not store together with food. Dispose waste as hazardous chemical to prevent personal injury and environmental pollution.
