As a certified reference material (CRM), 5α-Androst-1-ene-3α-ol-17-one (available to WADA laboratories only) 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.
CATO supplies 5α-Androst-1-ene-3α-ol-17-one (available to WADA laboratories only) (CAS 38859-37-9), a certified reference material (molecular formula C19H28O2, MW 288.42 g/mol) for analytical method development and quality control.
Owing to a steroid core, a hydroxyl group, an ether linkage, 5α-Androst-1-ene-3α-ol-17-one (available to WADA laboratories only) is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 288.42 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
