3-methyl-5-{[2-nitro-4-(trifluoromethyl)phenyl]sulphanyl}-4H-1,2,4-triazol-4-amine CAS 300664-71-5

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.

3-methyl-5-{[2-nitro-4-(trifluoromethyl)phenyl]sulphanyl}-4H-1,2,4-triazol-4-amine (CAS 300664-71-5), molecular formula C10H8F3N5O2S and molecular weight 319.26 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, fluorine substitution, 3-methyl-5-{[2-nitro-4-(trifluoromethyl)phenyl]sulphanyl}-4H-1,2,4-triazol-4-amine is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 319.26 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

As a certified reference material (CRM), 3-methyl-5-{[2-nitro-4-(trifluoromethyl)phenyl]sulphanyl}-4H-1,2,4-triazol-4-amine 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.
