Owing to a nitrogen-containing heterocyclic scaffold, a nitrile group, fluorine/chlorine substitution, 7-(3-Chloro-5-(trifluoromethyl)pyridin-2-yl)-5-methyl-[1,2,4]triazolo[1,5-a]pyrimidine is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 313.67 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
7-(3-Chloro-5-(trifluoromethyl)pyridin-2-yl)-5-methyl-[1,2,4]triazolo[1,5-a]pyrimidine (CAS 1048383-29-4) is a high-purity analytical reference standard with the molecular formula C12H7ClF3N5 and a molecular weight of 313.67 g/mol.
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.
