Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO supplies 2-methyl-5,6,7,8-tetrahydro-3H-pyrido[4,3-d]pyrimidin-4-one (CAS 134201-14-2), a certified reference material (molecular formula C8H15N3O, MW 169.22 g/mol) for analytical method development and quality control.
Owing to an amide group, a hydroxyl group, an ether linkage, 2-methyl-5,6,7,8-tetrahydro-3H-pyrido[4,3-d]pyrimidin-4-one is typically white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 169.22 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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.
