4-Amino-1-methyl-1H-pyrazolo[3,4-d]pyrimidine-3-carbonitrile CAS 42204-41-1

Description

The occurrence of 4-Amino-1-methyl-1H-pyrazolo[3,4-d]pyrimidine-3-carbonitrile is closely related to a nitrile group, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

4-Amino-1-methyl-1H-pyrazolo[3,4-d]pyrimidine-3-carbonitrile (CAS 42204-41-1), molecular formula C7H6N6 and molecular weight 174.16 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a nitrile group, an aromatic ring system, 4-Amino-1-methyl-1H-pyrazolo[3,4-d]pyrimidine-3-carbonitrile is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 174.16 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).

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.
