Chemical Structure
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.
CATO supplies 1-(4-Phenoxyphenyl)-5-(pyridin-4-yl)-1H-1,2,3-triazole-4-carboxylic acid (CAS 1326843-89-3), a certified reference material (molecular formula C20H14N4O3, MW 358.35 g/mol) for analytical method development and quality control.
Structurally, 1-(4-Phenoxyphenyl)-5-(pyridin-4-yl)-1H-1,2,3-triazole-4-carboxylic acid (C20H14N4O3) contains a steroid core, an amide group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 16.0, corresponding to approximately 16 ring(s) or double-bond equivalent(s). With a molecular weight of 358.35 g/mol, it falls into the moderately-high-molecular-weight range. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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.
