Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 207.62 g/mol gives 1-Phenyl-1H-1,2,3-triazole-4-carbonyl chloride distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies 1-Phenyl-1H-1,2,3-triazole-4-carbonyl chloride (CAS 134541-91-6), a certified reference material (molecular formula C9H6ClN3O, MW 207.62 g/mol) for analytical method development and quality control.
1-Phenyl-1H-1,2,3-triazole-4-carbonyl chloride (C9H6ClN3O) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. Halogen substitution raises its density and boiling point; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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.
