Chemical Structure

77171-24-5 Desulfoprogoitrin CAS 77171-24-5 chemical structure

Description

77171-24-5 Desulfoprogoitrin (CAS 77171-24-5), molecular formula C11H19NO7S and molecular weight 309.34 g/mol, is a CATO reference standard with documented purity and traceability.

77171-24-5 Desulfoprogoitrin (C11H19NO7S) contains an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage. It is notably hygroscopic, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.

CATO manufactures 77171-24-5 Desulfoprogoitrin 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.
