CATO supplies 5-Amino-N-(3,5-dimethylphenyl)-1-(4-methylbenzyl)-1H-1,2,3-triazole-4-carboxamide (CAS 845867-39-2), a certified reference material (molecular formula C19H21N5O, MW 335.40 g/mol) for analytical method development and quality control.
Structurally, 5-Amino-N-(3,5-dimethylphenyl)-1-(4-methylbenzyl)-1H-1,2,3-triazole-4-carboxamide (C19H21N5O) contains a steroid core, an amide group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 12.0, corresponding to approximately 12 ring(s) or double-bond equivalent(s). With a molecular weight of 335.40 g/mol, it falls into the moderately-high-molecular-weight range. 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.
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.
