Description

Trimethyl Citrate is a versatile organic ester derived from citric acid, serving as a key intermediate and functional additive in high-value industrial processes. Its primary value lies in its role as a building block for synthesizing more complex citrate esters and as a non-toxic plasticizer or chelating agent. This product is essential for manufacturers in the pharmaceutical, food additive, and polymer industries seeking reliable, high-purity raw materials.

Application

• Pharmaceutical Intermediate: Used in the synthesis of active pharmaceutical ingredients (APIs) and as an excipient in controlled-release formulations.
• Food & Beverage Additive: Functions as a flavoring agent, acidity regulator, and sequestrant in food-grade applications.
• Polymer & Plasticizer: Acts as a monomer or co-monomer in polymer production and as a non-toxic plasticizer for specialty polymers.
• Cosmetics & Personal Care: Employed as a buffering agent, chelator, and stabilizer in creams, lotions, and other formulations.
• Industrial Chelating Agent: Used in water treatment, metal cleaning, and as a component in detergent formulations for its metal-sequestering properties.
• Chemical Synthesis: Serves as a protected form of citric acid or a starting material for synthesizing other citrate esters and derivatives.
