Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
CATO supplies (2-((3R,5R)-3,5-Dihydroxycyclohexylidene)ethyl)diphenylphosphine oxide (CAS 883214-91-3), a certified reference material (molecular formula C20H23O3P, MW 342.37 g/mol) for analytical method development and quality control.
(2-((3R,5R)-3,5-Dihydroxycyclohexylidene)ethyl)diphenylphosphine oxide (C20H23O3P) contains a steroid core, a phosphonate 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.
