Hexadecanedioic acid

Hexadecanedioic acid (CAS 505-54-4), also known as thapsic acid, is a long-chain dicarboxylic acid used as a functional building block across specialty chemical formulations. Its bifunctional acid structure makes it a reactive intermediate for polymer synthesis.

This versatile chemical is essential for creating ester-based lubricants and advanced emulsifier systems. In lubricant and metalworking fluid formulations, it serves as a precursor to complex ester base fluids that deliver high-temperature stability.

These fluids are valued for providing low-friction performance in demanding industrial environments. Personal care manufacturers incorporate it into wax esters and emollient systems where controlled spreading and surface modification are required.

Food-grade ester derivatives produced from this acid are used as emulsifiers and release agents in processed food applications. In polymer chemistry, it functions as a diacid monomer for nylon and polyester synthesis.

The material contributes to the development of high-performance materials with defined chain length and thermal properties. Hexadecanedioic acid is supplied as a white crystalline powder or flake for easy handling.

Technical grade is the standard commercial form, with purity levels typically at 98% or higher. Food-grade and high-purity grades are available for applications requiring tighter specification compliance for global markets.

This includes ester synthesis destined for food or cosmetic end use where purity is critical. Our product meets rigorous industry requirements to ensure consistent performance across all manufacturing and synthesis batches.
