| General description: | 2-Propanol, also known as isopropyl alcohol, is a widely used solvent and disinfectant in microbiology. In biologics manufacturing, it plays a pivotal role in the preparation and cleaning of equipment to ensure contamination-free environments. Its quick evaporation rate and broad-spectrum antimicrobial activity make it an indispensable tool in maintaining the sterility of biologic products and pharmaceutical processes. 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. |
