Description

CATO supplies 80471-63-2 6375T36951 Epostane Epostane [USAN:INN:BAN] Androst-2-ene-2-carbonitrile, 4,5-epoxy-3,17-dihydroxy-4,17-dimethyl-, (4alpha,5alpha,17beta)- 4,5-epoxy-3,17-dihydroxy-4,17-dimethylandrost-2-ene-2-carbonitrile (4alpha,5alpha,17beta) Win 32729 Epostano [Spanish] Epostanum [Latin] Epostano Epostanum UNII-6375T36951 Win 32,729 (CAS 80471-63-2), a certified reference material (molecular formula C22H31NO3, MW 357.49 g/mol) for analytical method development and quality control.

80471-63-2 6375T36951 Epostane Epostane [USAN:INN:BAN] Androst-2-ene-2-carbonitrile, 4,5-epoxy-3,17-dihydroxy-4,17-dimethyl-, (4alpha,5alpha,17beta)- 4,5-epoxy-3,17-dihydroxy-4,17-dimethylandrost-2-ene-2-carbonitrile (4alpha,5alpha,17beta) Win 32729 Epostano [Spanish] Epostanum [Latin] Epostano Epostanum UNII-6375T36951 Win 32,729 (C22H31NO3) contains a steroid core, an amide 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 high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

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), 80471-63-2 6375T36951 Epostane Epostane [USAN:INN:BAN] Androst-2-ene-2-carbonitrile, 4,5-epoxy-3,17-dihydroxy-4,17-dimethyl-, (4alpha,5alpha,17beta)- 4,5-epoxy-3,17-dihydroxy-4,17-dimethylandrost-2-ene-2-carbonitrile (4alpha,5alpha,17beta) Win 32729 Epostano [Spanish] Epostanum [Latin] Epostano Epostanum UNII-6375T36951 Win 32,729 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.
