Dipicolinic acid

Dipicolinic acid (CAS 499-83-2 ), commonly abbreviated as DPA, is a pyridine-based dicarboxylic acid used across food, cosmetic, and industrial chemistry applications. It functions primarily as a chelating agent, catalyst precursor, and preservation-active compound in formulated systems. In food and flavoring applications, DPA acts as an acidulant and flavor modifier in processed formulations where precise pH control and taste profile adjustment are required. Its strong metal-chelating capacity makes it a valued precursor in catalyst preparation. This material is particularly useful for coordination complexes used in organic synthesis and polymerization processes. In personal care and cosmetic formulations, DPA contributes to preservation systems by disrupting microbial activity. By reducing reliance on conventional biocides, it offers a versatile solution for modern formulators. Industrial buyers also source it for use in analytical chemistry and as a reference standard for spore detection assays. DPA is a recognized biomarker for bacterial endospores, making it essential for specialized laboratory testing. Dipicolinic acid is supplied as a white to off-white crystalline powder for various industrial needs. It is available in technical grade for industrial and catalytic applications, as well as high-purity grades suited to analytical, food, and cosmetic end uses. Standard packaging ranges from laboratory-scale quantities to bulk orders. Contact us for supply of Dipicolinic acid Request Quote
