Description

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.

CATO supplies (Z)-2-(4-(4-(tert-butyl)phenyl)-3-methyl-5-oxo-4,5-dihydro-1H-1,2,4-triazol-1-yl)-N'-((4-fluorobenzoyl)oxy)acetimidamide (CAS 866038-35-9), a certified reference material (molecular formula C22H24FN5O3, MW 425.46 g/mol) for analytical method development and quality control.

Structurally, (Z)-2-(4-(4-(tert-butyl)phenyl)-3-methyl-5-oxo-4,5-dihydro-1H-1,2,4-triazol-1-yl)-N'-((4-fluorobenzoyl)oxy)acetimidamide (C22H24FN5O3) contains a steroid core, an amide group, a hydroxyl group, an ether linkage, fluorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 13.0, corresponding to approximately 13 ring(s) or double-bond equivalent(s). With a molecular weight of 425.46 g/mol, it falls into the moderately-high-molecular-weight range. 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).

As a certified reference material (CRM), (Z)-2-(4-(4-(tert-butyl)phenyl)-3-methyl-5-oxo-4,5-dihydro-1H-1,2,4-triazol-1-yl)-N'-((4-fluorobenzoyl)oxy)acetimidamide 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.
