Adipic acid, a key dicarboxylic acid with the chemical formula C6H10O4 and CAS number 124-04-9, serves as a fundamental intermediate in a vast range of chemical syntheses. Its bifunctional nature, featuring two carboxyl groups separated by a four-carbon chain, makes it an ideal building block for larger molecules and polymers. NINGBO INNO PHARMCHEM CO.,LTD. is a premier manufacturer and supplier of adipic acid in China, dedicated to supporting diverse industrial synthesis requirements.

The most significant use of adipic acid as an intermediate is in the production of polyamides, specifically nylon 66. This high-performance polymer is synthesized through a polycondensation reaction between adipic acid and hexamethylenediamine. The resulting nylon offers excellent mechanical properties, wear resistance, and thermal stability, making it indispensable in automotive parts, textiles, and industrial components. For manufacturers looking to buy adipic acid for these applications, our product’s high purity (≥99.80%) and consistent quality are critical for efficient polymerization and superior end-product performance.

Beyond polyamides, adipic acid is also a crucial intermediate for producing polyurethane elastomers. These versatile materials are known for their excellent abrasion resistance, tear strength, and flexibility, finding applications in footwear, coatings, and adhesives. The esters of adipic acid also serve as important intermediates for plasticizers and high-performance lubricants, contributing to improved product flexibility and operational efficiency. As a reliable supplier, we ensure our adipic acid provides the necessary purity for these esterification processes.

Furthermore, adipic acid is utilized in various other organic synthesis pathways. It acts as a flux in metal processing and as a raw material for synthetic dyes and spices. Its role as a food additive (E355), acting as an acidulant and gelling agent, also highlights its versatility as an intermediate in formulating consumer products. For businesses needing to purchase adipic acid, our competitive pricing and reliable supply chain from China position us as a preferred partner.
