Chemical Structure

Fiduxosin CAS 208993-54-8 chemical structure

Description

Fiduxosin (CAS 208993-54-8), molecular formula C30H29N5O4S and molecular weight 555.65 g/mol, is a CATO reference standard with documented purity and traceability.

Fiduxosin (C30H29N5O4S) contains a steroid core, an amide group, a sulfone 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 aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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.

As a certified reference material (CRM), Fiduxosin meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
