Pentadecanedioic acid

Pentadecanedioic acid (CAS 1460-18-0) is a long-chain aliphatic dicarboxylic acid used as a monomer and functional ingredient in specialty polymer, lubricant, and cosmetic applications.

Where is Pentadecanedioic acid used?

• Polymer chemistry: monomer for polyesters, polyamides, and specialty resins with longer chain segments to tune mechanical flexibility or melting behavior
• Lubricants: incorporated into ester-based base oils and additive packages, enabling diester lubricants with controlled viscosity profiles
• Personal care: plasticizer and emollient-active ingredient in film-forming and conditioning formulations for skin and hair
• Its reactivity with diols and diamines supports biodegradable polymer platforms.

Good to know: Its C15 chain length positions it between the more common C12 and C18 diacids, offering a balance of chain flexibility and reactivity that shorter-chain alternatives cannot replicate.

Commercial specifications

• Purity levels typically 95% to 98%+
• Packaging from small laboratory quantities to kilogram-scale orders
