Chemical Structure

7α-Thiomethylspironolactone sulfoxide CAS 38753-75-2 chemical structure

Description

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.

7α-Thiomethylspironolactone sulfoxide (CAS 38753-75-2), molecular formula C23H32O4S and molecular weight 404.56 g/mol, is a CATO reference standard with documented purity and traceability.

7α-Thiomethylspironolactone sulfoxide (C23H32O4S) contains a flavonoid core, a sulfone group, a hydroxyl group, an ether linkage. Its high carbon-to-hydrogen ratio confers good lipid solubility, 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).

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
