Chemical Structure
Description
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.
CATO supplies 5-Androsten-3β-ol-17-one Methanesulfonate (CAS 25810-70-2), a certified reference material (molecular formula C20H30O4S, MW 366.51 g/mol) for analytical method development and quality control.
Owing to a steroid core, a sulfone group, a hydroxyl group, an ether linkage, 5-Androsten-3β-ol-17-one Methanesulfonate is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 366.51 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).
As a certified reference material (CRM), 5-Androsten-3β-ol-17-one Methanesulfonate 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.
