Description

General description

Triethyl citrate is used in microbiology primarily as a plasticizer in the formulation of biologics, where it enhances the flexibility of polymeric materials. In biologic product development, it is also used as a stabilizing agent in vaccines and other injectable therapeutics. Its role in drug formulations is crucial for maintaining the integrity and performance of biologic products over time.

The United States Pharmacopeia (USP) provides quality standards for biologics to ensure their safety, efficacy, and quality throughout the manufacturing process. These standards assist manufacturers in adhering to regulatory requirements and help safeguard public health by reducing risks associated with biologics.

We are committed to bringing you Greener Alternative Products, which adhere to one or more of The 12 Principles of Green Chemistry. This product can replace highly toxic diluents in membrane preparation and thus aligns with "Less Hazardous Chemical Syntheses". Click here for more information.
