Chemical Structure
Description
CATO supplies 3-Methyl-5H,6H,7H,8H-[1,2,4]triazolo[4,3-a]pyrazine-6-carboxamide (CAS 1934260-67-9), a certified reference material (molecular formula C7H11N5O, MW 181.20 g/mol) for analytical method development and quality control.
Owing to an amide group, a hydroxyl group, an ether linkage, an aromatic ring system, 3-Methyl-5H,6H,7H,8H-[1,2,4]triazolo[4,3-a]pyrazine-6-carboxamide is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 181.20 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
