Description

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

N-([1,2,4]triazolo[4,3-a]quinoxalin-4-yl)-O-(4-chlorobenzyl)hydroxylamine (CAS 245039-35-4), molecular formula C16H12ClN5O and molecular weight 325.75 g/mol, is a CATO reference standard with documented purity and traceability.

Based on its molecular formula C16H12ClN5O, N-([1,2,4]triazolo[4,3-a]quinoxalin-4-yl)-O-(4-chlorobenzyl)hydroxylamine contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 325.75 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.
