3-Amino-1-methyl-4-(thiophen-2-yl)-1,4,5,7-tetrahydro-6H-pyrazolo[3,4-b]pyridin-6-one CAS 1105190-99-5

Description

Owing to a nitrogen-containing heterocyclic scaffold, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, 3-Amino-1-methyl-4-(thiophen-2-yl)-1,4,5,7-tetrahydro-6H-pyrazolo[3,4-b]pyridin-6-one is typically pale yellow to yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 248.30 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.

3-Amino-1-methyl-4-(thiophen-2-yl)-1,4,5,7-tetrahydro-6H-pyrazolo[3,4-b]pyridin-6-one (CAS 1105190-99-5), molecular formula C11H12N4OS and molecular weight 248.30 g/mol, is a CATO reference standard with documented purity and traceability.

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.

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.
