4,5-Epoxy-19-nortestosterone CAS 52153-24-9

Description

Compared with other compounds in its class, the molecular weight of 290.40 g/mol gives 4,5-Epoxy-19-nortestosterone distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

4,5-Epoxy-19-nortestosterone (CAS 52153-24-9), molecular formula C18H26O3 and molecular weight 290.40 g/mol, is a CATO reference standard with documented purity and traceability.

4,5-Epoxy-19-nortestosterone (C18H26O3) 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), 4,5-Epoxy-19-nortestosterone 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.
