CATO supplies K5ZM856PSA 130447-37-9 1,25-Dihydroxy-19-norvitamin D3 19-Nor-9,10-secocholesta-5,7-diene-1,3,25-triol, (1alpha,3beta,7E)- 20-Epi-19-nor-1,25-(OH)2 D3 19-Nor-22(E) 1alpha,25-(OH)2-19-Nor-vitamin D3 UNII-K5ZM856PSA (CAS 130447-37-9), a certified reference material (molecular formula C26H44O3, MW 404.63 g/mol) for analytical method development and quality control.

K5ZM856PSA 130447-37-9 1,25-Dihydroxy-19-norvitamin D3 19-Nor-9,10-secocholesta-5,7-diene-1,3,25-triol, (1alpha,3beta,7E)- 20-Epi-19-nor-1,25-(OH)2 D3 19-Nor-22(E) 1alpha,25-(OH)2-19-Nor-vitamin D3 UNII-K5ZM856PSA (C26H44O3) 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 presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

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), K5ZM856PSA 130447-37-9 1,25-Dihydroxy-19-norvitamin D3 19-Nor-9,10-secocholesta-5,7-diene-1,3,25-triol, (1alpha,3beta,7E)- 20-Epi-19-nor-1,25-(OH)2 D3 19-Nor-22(E) 1alpha,25-(OH)2-19-Nor-vitamin D3 UNII-K5ZM856PSA 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.
