Chemical Structure
Description
As a certified reference material (CRM), 11α-Hydroxy-16,17α-epoxyprogesterone 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.
CATO supplies 11α-Hydroxy-16,17α-epoxyprogesterone (CAS 19427-36-2), a certified reference material (molecular formula C21H28O4, MW 344.44 g/mol) for analytical method development and quality control.
11α-Hydroxy-16,17α-epoxyprogesterone (C21H28O4) contains a flavonoid 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.
