Description

General description

Find answers to frequently asked questions on USP products in USP FAQs.

Methyl ethyl ketone is a solvent used in biologic and pharmaceutical applications. Its role is particularly crucial in the extraction and purification of biologic compounds, as well as in formulations where its quick evaporation properties help ensure product stability. MEK is valuable in the preparation of drug delivery systems, contributing to the efficient dissolution of active pharmaceutical ingredients.

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.
