Tetradecanedioic acid (CAS No. 821-38-5), also known as 1,12-Dodecanedicarboxylic acid, 1,14-tetradecanedioic acid or DC14, is an organic dicarboxylic acid with the chemical formula C14H26O4. Produced via an advanced bio-fermentation process exclusively by NOVACID. It is characterized by the fact that it has a straight carbon chain with two terminal carboxylic acid functional groups (-COOH). 

1. Flavors and Fragrances
- Tetradecanedioic acid serves as a high-purity intermediate for synthesizing premium long-chain esters and lactones, which are core ingredients in fine fragrances and food flavors. Its stable molecular structure ensures the synthesized aroma compounds have a long-lasting, mellow scent profile, free from off-notes caused by impurities. Widely used in formulating floral, fruity and woody fragrances for cosmetics, perfumes and household products, as well as enhancing the natural flavor of baked goods, confectionery and beverages with subtle, pleasant undertones.
2. High-Performance Engineering Plastics
- As a core monomer for synthesizing PA1414, PA614 and PA1014 polyamides, tetradecanedioic acid enhances the materials’ wear resistance, chemical stability and low-temperature toughness. These advanced polyamides are widely used in automotive transmission components, aerospace structural parts, and high-precision electronic connectors.
3. Specialty Synthetic Lubricants
- It serves as a key raw material for producing high-grade ester-based lubricants with a high viscosity index, low volatility and excellent thermal oxidation stability. These lubricants are ideal for new energy vehicle motors, industrial gearboxes and precision instrument bearings.
4. Advanced Coatings & Adhesives
- Tetradecanedioic acid is utilized in manufacturing low-VOC, high-solid-content anti-corrosion coatings and structural adhesives. The finished products deliver superior adhesion to metal, plastic and composite substrates, and are applied in marine engineering, pipeline anticorrosion and aerospace component bonding.
5. Fine Chemicals & Functional Materials
- It acts as an intermediate for synthesizing biodegradable surfactants, textile auxiliaries and plasticizers, offering excellent environmental compatibility and performance advantages over traditional short-chain alternatives. It is also used in producing high-grade cosmetic emollients and pharmaceutical excipients.
