5-Amino-1-(m-tolyl)-1,5-dihydro-4H-pyrazolo[3,4-d]pyrimidin-4-one CAS 1416339-41-7

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 5-Amino-1-(m-tolyl)-1,5-dihydro-4H-pyrazolo[3,4-d]pyrimidin-4-one (CAS 1416339-41-7), a certified reference material (molecular formula C12H11N5O, MW 241.25 g/mol) for analytical method development and quality control.

Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, 5-Amino-1-(m-tolyl)-1,5-dihydro-4H-pyrazolo[3,4-d]pyrimidin-4-one is typically pale yellow to yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 241.25 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.
