N-(4-chloro-3-nitrophenyl)-2-((4-methyl-5-(trifluoromethyl)-4H-1,2,4-triazol-3-yl)thio)acetamide CAS 329778-13-4

Description

As a certified reference material (CRM), N-(4-chloro-3-nitrophenyl)-2-((4-methyl-5-(trifluoromethyl)-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-(4-chloro-3-nitrophenyl)-2-((4-methyl-5-(trifluoromethyl)-4H-1,2,4-triazol-3-yl)thio)acetamide (CAS 329778-13-4) is a high-purity analytical reference standard with the molecular formula C12H9ClF3N5O3S and a molecular weight of 395.74 g/mol.

The molecular framework of N-(4-chloro-3-nitrophenyl)-2-((4-methyl-5-(trifluoromethyl)-4H-1,2,4-triazol-3-yl)thio)acetamide (C12H9ClF3N5O3S) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution. 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. 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.
