Chemical Structure
Description
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
CATO supplies 1-(2,4-Dichlorobenzyl)-1h-1,2,3-triazol-4-amine (CAS 1443290-34-3), a certified reference material (molecular formula C9H8Cl2N4, MW 243.09 g/mol) for analytical method development and quality control.
1-(2,4-Dichlorobenzyl)-1h-1,2,3-triazol-4-amine (C9H8Cl2N4) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, chlorine substitution. Halogen substitution raises its density and boiling point; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
