Chemical Structure
Description
Owing to a steroid core, a hydroxyl group, an ether linkage, 2, (5α)-ANDROSTEN-17β-OL is typically off-white to pale yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 274.44 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
2, (5α)-ANDROSTEN-17β-OL (CAS 2639-53-4) is a high-purity analytical reference standard with the molecular formula C19H30O and a molecular weight of 274.44 g/mol.
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), 2, (5α)-ANDROSTEN-17β-OL 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.
