Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
4-Amino-benzoic acid 1H-benzoimidazol-2-ylmethylester hydrochloride (CAS 435342-18-0), molecular formula C15H13N3O2 and molecular weight 267.28 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 4-Amino-benzoic acid 1H-benzoimidazol-2-ylmethylester hydrochloride (C15H13N3O2) is characterized by a nitrogen-containing heterocyclic scaffold, 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.
