Chemical Structure
Description
The occurrence of 6-(4-Chlorophenyl)-5-methyl-[1,2,4]triazolo[1,5-a]pyrimidin-7-amine is closely related to a nitrogen-containing heterocyclic scaffold, a nitrile group, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies 6-(4-Chlorophenyl)-5-methyl-[1,2,4]triazolo[1,5-a]pyrimidin-7-amine (CAS 922186-91-2), a certified reference material (molecular formula C12H10ClN5, MW 259.69 g/mol) for analytical method development and quality control.
6-(4-Chlorophenyl)-5-methyl-[1,2,4]triazolo[1,5-a]pyrimidin-7-amine (C12H10ClN5) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, 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.
