Chemical Structure
Description
CATO manufactures Leupeptin hemisulfate hydrate under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
CATO supplies Leupeptin hemisulfate hydrate (CAS 1082207-96-2), a certified reference material (molecular formula C20H38N6O4H2O4SH2O, MW 542.65 g/mol) for analytical method development and quality control.
Based on its molecular formula C20H38N6O4H2O4SH2O, Leupeptin hemisulfate hydrate contains an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 542.65 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
