Benzimidazoles are a class of heterocyclic compounds that form the structural core of numerous pharmaceuticals, agrochemicals, and functional materials. Their significance in modern chemistry is undeniable, and the efficient synthesis of these versatile molecules relies heavily on specific precursor intermediates. Among these, 4-Amino-3-nitrobenzophenone, identified by its CAS number 31431-19-3, plays a particularly crucial role. This yellow powder (C13H10N2O3) is a key enabler for constructing the characteristic benzimidazole ring system, making it an indispensable compound for chemists engaged in synthesis and product development.

The synthesis of benzimidazoles typically involves the cyclocondensation of an ortho-phenylenediamine derivative with a carboxylic acid or its equivalent. 4-Amino-3-nitrobenzophenone, upon appropriate chemical transformation (often reduction of the nitro group to an amine), effectively provides the necessary ortho-diamine functionality adjacent to a benzoyl group. This structural feature makes it an exceptionally useful starting material for creating substituted benzimidazoles with tailored properties. For R&D scientists aiming to develop new compounds, understanding how to effectively utilize and buy this intermediate is a significant advantage.

The utility of 4-Amino-3-nitrobenzophenone isn't limited to simple benzimidazoles. It also serves as a precursor for more complex fused ring systems, such as imidazolopyridines, which possess their own unique set of applications. The demand for these types of heterocycles in pharmaceutical research, particularly for antiviral, anticancer, and antimicrobial agents, is substantial. Manufacturers and researchers seeking to develop these advanced molecules often turn to reliable suppliers of intermediates like 4-Amino-3-nitrobenzophenone. NINGBO INNO PHARMCHEM CO.,LTD., as a dedicated manufacturer and supplier in China, offers this compound to meet these critical needs, providing consistent quality and enabling efficient production.

For procurement managers, the strategic sourcing of such vital intermediates is key to ensuring project timelines and cost-effectiveness. Identifying manufacturers with robust quality control, substantial production capacity, and a proven track record is essential. When looking for '4-amino-3-nitrobenzophenone price' or exploring options to purchase CAS 31431-19-3, engaging with experienced chemical suppliers is recommended. These suppliers can offer not only competitive pricing but also technical support and reliable logistics, ensuring that your supply chain remains robust.

In conclusion, 4-Amino-3-nitrobenzophenone (CAS 31431-19-3) is a critical intermediate that unlocks efficient pathways to benzimidazoles and related heterocyclic compounds. Its strategic importance in pharmaceutical synthesis and fine chemical manufacturing underscores the need for reliable sourcing.
