Chemical Structure

5α-Pregnan-3β,20α-diol 3-sulfate-D4 (as potassium salt) CAS CATO-C4X-24432 chemical structure

Description

CATO supplies 5α-Pregnan-3β,20α-diol 3-sulfate-D4 (as potassium salt) (CAS CATO-C4X-24432), a certified reference material (molecular formula C21H31D4O5SK, MW 442.69 g/mol) for analytical method development and quality control.

Owing to deuterium isotope labeling, a steroid core, a sulfone group, a hydroxyl group, an ether linkage, 5α-Pregnan-3β,20α-diol 3-sulfate-D4 (as potassium salt) is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 442.69 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).

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 manufactures 5α-Pregnan-3β,20α-diol 3-sulfate-D4 (as potassium salt) under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
