Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 5,9-(Epoxymethano)-2H-cyclopenta[a]phenanthren-3-ol, 20-ethoxy-17-[(1R,3E)-5-hydroxy-1,5-dimethyl-3-hexen-1-yl]-1,3,4,8,10,11,12,13,14,15,16,17-dodecahydro-4,4,13,14-tetramethyl-, (3S,5R,8S,9S,10S,13R,14S,17R,20R)-.

CATO supplies 5,9-(Epoxymethano)-2H-cyclopenta[a]phenanthren-3-ol, 20-ethoxy-17-[(1R,3E)-5-hydroxy-1,5-dimethyl-3-hexen-1-yl]-1,3,4,8,10,11,12,13,14,15,16,17-dodecahydro-4,4,13,14-tetramethyl-, (3S,5R,8S,9S,10S,13R,14S,17R,20R)- (CAS 1301267-02-6), a certified reference material (molecular formula C32H52O4, MW 500.75 g/mol) for analytical method development and quality control.

5,9-(Epoxymethano)-2H-cyclopenta[a]phenanthren-3-ol, 20-ethoxy-17-[(1R,3E)-5-hydroxy-1,5-dimethyl-3-hexen-1-yl]-1,3,4,8,10,11,12,13,14,15,16,17-dodecahydro-4,4,13,14-tetramethyl-, (3S,5R,8S,9S,10S,13R,14S,17R,20R)- (C32H52O4) contains a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system. 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.

As a certified reference material (CRM), 5,9-(Epoxymethano)-2H-cyclopenta[a]phenanthren-3-ol, 20-ethoxy-17-[(1R,3E)-5-hydroxy-1,5-dimethyl-3-hexen-1-yl]-1,3,4,8,10,11,12,13,14,15,16,17-dodecahydro-4,4,13,14-tetramethyl-, (3S,5R,8S,9S,10S,13R,14S,17R,20R)- 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.
