Description
CATO manufactures 5-chloro-3-methyl-triazolo[4,5-b]pyridine under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
CATO supplies 5-chloro-3-methyl-triazolo[4,5-b]pyridine (CAS 1353777-54-4), a certified reference material (molecular formula C6H13ClN4, MW 176.65 g/mol) for analytical method development and quality control.
Owing to a nitrile group, chlorine substitution, 5-chloro-3-methyl-triazolo[4,5-b]pyridine is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 176.65 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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.
