Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 5α-ANDROSTAN-3β-OL-17β-CARBOXYLIC ACID.
5α-ANDROSTAN-3β-OL-17β-CARBOXYLIC ACID (CAS 15173-54-3), molecular formula C20H32O3 and molecular weight 320.47 g/mol, is a CATO reference standard with documented purity and traceability.
5α-ANDROSTAN-3β-OL-17β-CARBOXYLIC ACID (C20H32O3) contains 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-ANDROSTAN-3β-OL-17β-CARBOXYLIC ACID 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.
