Chemical Structure
Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
3-(5-(Hydroxymethyl)-1H-1,2,3-triazol-1-yl)benzoic acid (CAS 473548-18-4), molecular formula C10H9N3O3 and molecular weight 219.20 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 3-(5-(Hydroxymethyl)-1H-1,2,3-triazol-1-yl)benzoic acid (C10H9N3O3) is characterized by an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.
