Chemical Structure

5α-Androstane-3α,17β-diol-[d3]100ug/ml in Methanol CAS 79037-33-5 chemical structure

Description

The occurrence of 5α-Androstane-3α,17β-diol-[d3]100ug/ml in Methanol is closely related to deuterium isotope labeling, a steroid core, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

5α-Androstane-3α,17β-diol-[d3]100ug/ml in Methanol (CAS 79037-33-5), molecular formula C19H29D3O2 and molecular weight 295.47 g/mol, is a CATO reference standard with documented purity and traceability.

5α-Androstane-3α,17β-diol-[d3]100ug/ml in Methanol (C19H29D3O2) contains deuterium isotope labeling, a steroid core, a hydroxyl group, an ether linkage. Its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

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), 5α-Androstane-3α,17β-diol-[d3]100ug/ml in Methanol 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.
