Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including (6a,11β,16a,17a)-17-(Acetyloxy)-6,9-difluoro-11-hydroxy-16-methyl-3-oxo-androsta-1,4-diene-17-carbothioic Acid S-(Iodomethyl) Ester.
CATO supplies (6a,11β,16a,17a)-17-(Acetyloxy)-6,9-difluoro-11-hydroxy-16-methyl-3-oxo-androsta-1,4-diene-17-carbothioic Acid S-(Iodomethyl) Ester (CAS 80474-71-1), a certified reference material (molecular formula C24H29F2IO5S, MW 594.45 g/mol) for analytical method development and quality control.
(6a,11β,16a,17a)-17-(Acetyloxy)-6,9-difluoro-11-hydroxy-16-methyl-3-oxo-androsta-1,4-diene-17-carbothioic Acid S-(Iodomethyl) Ester (C24H29F2IO5S) contains a flavonoid core, a sulfone group, a hydroxyl group, an ether linkage, fluorine/iodine substitution. Halogen substitution raises its density and boiling point, 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.
