Description

As a certified reference material (CRM), N-(2-Cyano-3-methylbutan-2-yl)-2-((5-methyl-4-phenyl-4H-1,2,4-triazol-3-yl)thio)propanamide 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 N-(2-Cyano-3-methylbutan-2-yl)-2-((5-methyl-4-phenyl-4H-1,2,4-triazol-3-yl)thio)propanamide (CAS 851280-87-0), a certified reference material (molecular formula C18H23N5OS, MW 357.47 g/mol) for analytical method development and quality control.

Structurally, N-(2-Cyano-3-methylbutan-2-yl)-2-((5-methyl-4-phenyl-4H-1,2,4-triazol-3-yl)thio)propanamide (C18H23N5OS) contains a steroid core, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 10.0, corresponding to approximately 10 ring(s) or double-bond equivalent(s). With a molecular weight of 357.47 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).

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.
