Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including (8R,9S,10S,13S,14S)-13-methyl-3,17-dioxo-1,2,3,6,7,8,9,11,12,13,14,15,16,17-tetradecahydro-10H-cyclopenta[a]phenanthrene-10-carbaldehyde.
CATO supplies (8R,9S,10S,13S,14S)-13-methyl-3,17-dioxo-1,2,3,6,7,8,9,11,12,13,14,15,16,17-tetradecahydro-10H-cyclopenta[a]phenanthrene-10-carbaldehyde (CAS 968-49-0), a certified reference material (molecular formula C19H24O3, MW 300.39 g/mol) for analytical method development and quality control.
(8R,9S,10S,13S,14S)-13-methyl-3,17-dioxo-1,2,3,6,7,8,9,11,12,13,14,15,16,17-tetradecahydro-10H-cyclopenta[a]phenanthrene-10-carbaldehyde (C19H24O3) contains a steroid core, 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 aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
