Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including (4R)-Methyl 4-((3R,8S,10S,13S,14S)-3-acetoxy-10,13-dimethyl-2,3,4,5,6,7,8,10,12,13,14,15-dodecahydro-1H-cyclopenta[a]phenanthren-17-yl)pentanoate.
(4R)-Methyl 4-((3R,8S,10S,13S,14S)-3-acetoxy-10,13-dimethyl-2,3,4,5,6,7,8,10,12,13,14,15-dodecahydro-1H-cyclopenta[a]phenanthren-17-yl)pentanoate (CAS 1093397-71-7) is a high-purity analytical reference standard with the molecular formula C27H40O4 and a molecular weight of 428.60 g/mol.
Owing to a steroid core, a hydroxyl group, an ether linkage, (4R)-Methyl 4-((3R,8S,10S,13S,14S)-3-acetoxy-10,13-dimethyl-2,3,4,5,6,7,8,10,12,13,14,15-dodecahydro-1H-cyclopenta[a]phenanthren-17-yl)pentanoate is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 428.60 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
As a certified reference material (CRM), (4R)-Methyl 4-((3R,8S,10S,13S,14S)-3-acetoxy-10,13-dimethyl-2,3,4,5,6,7,8,10,12,13,14,15-dodecahydro-1H-cyclopenta[a]phenanthren-17-yl)pentanoate 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.
