Description

Amino Acid Sequence

Glp-His-Trp-Ser-Tyr-Leu-Leu-Arg-Pro-NHEt

General description

Leuprolide acetate is a synthetic nonapeptide agonist of gonadotropin-releasing hormone (GnRH), used in the treatment of hormone-responsive cancers and reproductive disorders. It functions by downregulating pituitary gonadotropin secretion. The USP standard supports identity, potency, and impurity testing in peptide formulations.

The USP biologics peptides category encompasses a diverse range of therapeutic peptides that are essential in managing various medical conditions. These peptides, typically consisting of amino acid sequences of 40 residues or less, are critical for the development of high-quality medicines. The USP provides comprehensive standards, reference materials, and analytical procedures to ensure the identity, quality, purity, and consistency of peptide therapeutics throughout their lifecycle.

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.

Application

Leuprolide Acetate USP reference standard is used to prepare standard solutions for the identification, assay, and determination of the purity of leuprolide acetate. Further information is available in monograph, Leuprolide Acetate, USP43-NF38 – 2572 of United States Pharmacopeia (USP).
