N-(2-Cyano-3-methylbutan-2-yl)-2-((5-(4-ethylphenyl)-4H-1,2,4-triazol-3-yl)thio)acetamide CAS 854138-19-5

Description

As a certified reference material (CRM), N-(2-Cyano-3-methylbutan-2-yl)-2-((5-(4-ethylphenyl)-4H-1,2,4-triazol-3-yl)thio)acetamide 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.

N-(2-Cyano-3-methylbutan-2-yl)-2-((5-(4-ethylphenyl)-4H-1,2,4-triazol-3-yl)thio)acetamide (CAS 854138-19-5), molecular formula C18H23N5OS and molecular weight 357.47 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of N-(2-Cyano-3-methylbutan-2-yl)-2-((5-(4-ethylphenyl)-4H-1,2,4-triazol-3-yl)thio)acetamide (C18H23N5OS) is characterized by a steroid core, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

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.
