Description

Bis(3,7-Dimethyloctyl) Oxalate is a high-purity diester compound derived from oxalic acid and a branched-chain alcohol. This specialty chemical is valued for its role as a versatile intermediate and performance additive in advanced formulations. It is particularly sought after by manufacturers in the fragrance, polymer, and specialty lubricant industries seeking to enhance product characteristics such as stability, scent profile, or plasticizing effects.

Application

• Fragrance and Perfumery Industry: Acts as a valuable intermediate or fixative in the synthesis of complex aroma chemicals, contributing to long-lasting and stable scent profiles.
• Polymer and Plastic Additives: Serves as a specialty plasticizer or co-monomer for modifying the flexibility, processability, and thermal properties of specific polymer systems.
• Lubricant and Grease Formulation: Used as a synthetic base oil or performance additive to improve viscosity index, thermal stability, and lubricity in high-end industrial and synthetic lubricants.
• Chemical Synthesis: Functions as a key building block or protecting group reagent in organic synthesis for pharmaceuticals and agrochemicals.
• Cosmetics and Personal Care: Employed as an emollient or solvent in high-performance cosmetic formulations where specific ester properties are required.
