1-[1-(4-Methylphenyl)-6-(methylsulfanyl)-1H-pyrazolo[3,4-d]pyrimidin-4-yl]piperidine CAS 339106-50-2

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 1-[1-(4-Methylphenyl)-6-(methylsulfanyl)-1H-pyrazolo[3,4-d]pyrimidin-4-yl]piperidine.

1-[1-(4-Methylphenyl)-6-(methylsulfanyl)-1H-pyrazolo[3,4-d]pyrimidin-4-yl]piperidine (CAS 339106-50-2), molecular formula C18H21N5S and molecular weight 339.46 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 1-[1-(4-Methylphenyl)-6-(methylsulfanyl)-1H-pyrazolo[3,4-d]pyrimidin-4-yl]piperidine (C18H21N5S) is characterized by a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

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.
