Leuprolide Acetate EP Impurity C (CAS No. NA), chemically known as (S)-N-Ethyl-1-(((S)-5-oxopyrrolidine-2-carbonyl)-L-histidyl-L-tryptophyl-L-seryl-L-tyrosyl-L-leucyl-L-leucyl-L-arginyl)pyrrolidine-2-carboxamide acetate, is a well-characterized pharmaceutical impurity reference standard associated with Leuprolide. It is widely used by pharmaceutical research laboratories, analytical scientists, contract research organizations (CROs), and quality control laboratories to support impurity identification, chromatographic method development, analytical method validation, and stability studies.

This reference standard plays an important role in ensuring accurate impurity profiling during the development and quality assessment of Leuprolide-based pharmaceutical products. It is suitable for use in analytical techniques such as HPLC, LC-MS, UPLC, and other validated chromatographic methods where reliable impurity characterization is required.

Leuprolide Acetate EP Impurity C has the molecular formula C59H84N16O12 : n(C2H4O2) and a molecular weight of 1209.4: n(60.1) g/mol. It is also known by the chemical name (S)-N-Ethyl-1-(((S)-5-oxopyrrolidine-2-carbonyl)-L-histidyl-L-tryptophyl-L-seryl-L-tyrosyl-L-leucyl-L-leucyl-L-arginyl)pyrrolidine-2-carboxamide acetate and is identified by CAS No. NA.

Researchers and analytical laboratories utilize this impurity reference standard during pharmaceutical development, quality control testing, method transfer, and regulatory compliance activities. Its use helps support the characterization and monitoring of related substances throughout the product lifecycle.
