Product Application
In the U.S. market, glycine is mainly supplied in two grades: USP (United States Pharmacopeia) and technical grade. The USP grade accounts for about 80%–85% of total sales and serves a wide range of applications. Pharmaceutical-grade glycine meets stricter purity standards for uses such as intravenous injections, often exceeding USP requirements. It is usually manufactured under custom specifications and priced higher than standard USP-grade glycine.
