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.
5,6-Dehydro-17α-methyl-d3 Epiandrosterone (1.0mg/ml in Acetonitrile) (CAS 99371-94-5), molecular formula C20H29D3O2 and molecular weight 307.49 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to deuterium isotope labeling, a steroid core, a hydroxyl group, an ether linkage, 5,6-Dehydro-17α-methyl-d3 Epiandrosterone (1.0mg/ml in Acetonitrile) is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 307.49 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).
As a certified reference material (CRM), 5,6-Dehydro-17α-methyl-d3 Epiandrosterone (1.0mg/ml in Acetonitrile) 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.
