Benzathine benzylpenicillin for peak identification CRS refers to a Certified Reference Standard (CRS) used specifically in analytical testing to identify and confirm the characteristic peaks of benzathine benzylpenicillin in techniques like HPLC (High-Performance Liquid Chromatography). These reference standards ensure accurate identification, purity assessment, and consistency of pharmaceutical products. Using a CRS for peak identification helps laboratories verify that the sample contains the correct active ingredient and meets regulatory quality requirements.
