Description
CATO manufactures N-[(Z)-2-[4-Methyl-5-(trifluoromethyl)-4H-1,2,4-triazol-3-yl]-2-nitroethenyl]aniline under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
CATO supplies N-[(Z)-2-[4-Methyl-5-(trifluoromethyl)-4H-1,2,4-triazol-3-yl]-2-nitroethenyl]aniline (CAS 338402-50-9), a certified reference material (molecular formula C12H10F3N5O2, MW 313.24 g/mol) for analytical method development and quality control.
Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine substitution, N-[(Z)-2-[4-Methyl-5-(trifluoromethyl)-4H-1,2,4-triazol-3-yl]-2-nitroethenyl]aniline is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 313.24 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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.
