Sodium 3-nitrobenzoate

Sodium 3-nitrobenzoate (CAS 827-95-2), also referred to as sodium m-nitrobenzoate or sodium meta-nitrobenzoate, is the sodium salt of 3-nitrobenzoic acid. It carries no assigned E-code and is classified under salts and minerals with the molecular formula C7H5NO4.Na.

In pharmaceutical synthesis, it serves as a pH buffer and reaction intermediate, helping stabilise formulation environments where precise acidity control is critical. In agrochemical manufacturing, it functions as a catalyst or co-reagent in the production of active ingredients. Printing and packaging applications use it in dye and pigment chemistry where controlled reactivity is required.

Sodium 3-nitrobenzoate is supplied as a crystalline solid and falls under REACH regulation within the European market. It is classified under HS code 29163990 for customs purposes. Procurement teams should confirm grade specifications and documentation requirements directly with the supplier to ensure compliance with sector-specific standards.
