Pharmaceutical Materials

Ortho-Benzoylbenzoic acid (CAS No. 85-52-9), also known as 2-Benzoylbenzoic acid or BB acid, is a vital intermediate in organic synthesis, particularly in the production of anthraquinone-based dyes and pharmaceuticals. With a molecular formula of C₁₄H₁₀O₃ and a molecular weight of 226.23 g/mol, it exhibits characteristic properties such as a melting point of 126-130°C and solubility in ethanol, ether, and hot benzene. Its primary industrial applications include manufacturing dyes like anthraquinone and 1-aminoanthraquinone, as well as serving as a precursor in pharmaceutical intermediates. The compound is synthesized via Friedel-Crafts acylation of benzene with benzoyl chloride, followed by hydrolysis. Despite its utility, it is classified as an irritant (Xi) with potential hazards to eyes, skin, and respiratory systems, necessitating proper handling and storage under controlled conditions to ensure safety and efficacy in industrial processes.

Usage： It is an important dye and pharmaceutical intermediate.

Packaging and Shipping： 25KG/drum or as per buyer’s requirements.

Storage: Storage in ventilated low temperature dry warehouse; Keep container closed and separately from open flame and heat source.
