General description

Naphthalene is a polycyclic aromatic hydrocarbon that is occasionally used in biologics formulations, particularly in processes where its role as a solvent or stabilizer is beneficial. In the biologics industry, naphthalene is valued for its ability to interact with certain bioactive molecules, helping to stabilize compounds in formulations and enhancing their efficacy in therapeutic applications.

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.
