Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 17-(3,3-Dimethoxy-propyl)-10,13-dimethyl-1,2,3,4,7,8,9,10,11,12,13,14,15,16,17,20-hexadecahydro-cyclopropa[15,16]cyclopenta[a]phenanthrene-3,17-diol.

CATO supplies 17-(3,3-Dimethoxy-propyl)-10,13-dimethyl-1,2,3,4,7,8,9,10,11,12,13,14,15,16,17,20-hexadecahydro-cyclopropa[15,16]cyclopenta[a]phenanthrene-3,17-diol (CAS 67372-66-1), a certified reference material (molecular formula C25H40O4, MW 404.58 g/mol) for analytical method development and quality control.

Based on its molecular formula C25H40O4, 17-(3,3-Dimethoxy-propyl)-10,13-dimethyl-1,2,3,4,7,8,9,10,11,12,13,14,15,16,17,20-hexadecahydro-cyclopropa[15,16]cyclopenta[a]phenanthrene-3,17-diol contains a steroid core, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 404.58 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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), 17-(3,3-Dimethoxy-propyl)-10,13-dimethyl-1,2,3,4,7,8,9,10,11,12,13,14,15,16,17,20-hexadecahydro-cyclopropa[15,16]cyclopenta[a]phenanthrene-3,17-diol 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.
