Chemical Structure
Description
CATO supplies 3-chloro-[1,2,4]triazolo[4,3-a]pyridine (CAS 4922-74-1), a certified reference material (molecular formula C6H12ClN3, MW 161.63 g/mol) for analytical method development and quality control.
Based on its molecular formula C6H12ClN3, 3-chloro-[1,2,4]triazolo[4,3-a]pyridine contains a nitrile group, chlorine substitution; these features give the compound characteristic molecular-ion distribution patterns in mass spectrometry. The molecular weight of 161.63 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.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
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.
