Chemical Structure

5α-ANDROSTAN-3, 6, 17-TRIONE CAS 2243-05-2 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.

5α-ANDROSTAN-3, 6, 17-TRIONE (CAS 2243-05-2), molecular formula C19H26O3 and molecular weight 302.41 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a steroid core, a hydroxyl group, an ether linkage, 5α-ANDROSTAN-3, 6, 17-TRIONE is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 302.41 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), 5α-ANDROSTAN-3, 6, 17-TRIONE 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.
