Glutaric acid

Glutaric acid (CAS 110-94-1), also known commercially as glutarate, is a five-carbon dicarboxylic acid used across pharmaceutical, cosmetic, and food applications as a pH buffer, acidulant, and reactive intermediate.

Its bifunctional acid structure makes it a practical building block for synthesis and a reliable acidifying agent in formulated products. In pharmaceutical manufacturing, it functions as a co-former in active pharmaceutical ingredient salt development.

This material is essential for cocrystal development, improving solubility and stability profiles of drug candidates. Personal care formulators incorporate it as a mild acidulant and buffering agent in skin care products.

Controlled pH levels directly affect preservative efficacy and product shelf life in cosmetic formulations. In food and flavoring applications, it contributes a clean, mild acidic note and supports preservation in processed food systems.

It also serves as a precursor in the synthesis of polyesters, plasticizers, and specialty polymers used across industrial coating and resin formulations. The product is supplied as a white crystalline powder for easy handling.

Food-grade and pharmaceutical-grade material is available, with the latter typically conforming to USP or BP specifications. Technical-grade material is also offered for industrial synthesis and polymer applications.
