Chemical Structure

1-(4-Chloro-2-methylphenyl)-4-(pyrrolidin-1-yl)-1H-pyrazolo[3,4-d]pyrimidine CAS 921539-24-4 chemical structure

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 1-(4-Chloro-2-methylphenyl)-4-(pyrrolidin-1-yl)-1H-pyrazolo[3,4-d]pyrimidine.

1-(4-Chloro-2-methylphenyl)-4-(pyrrolidin-1-yl)-1H-pyrazolo[3,4-d]pyrimidine (CAS 921539-24-4) is a high-purity analytical reference standard with the molecular formula C16H16ClN5 and a molecular weight of 313.78 g/mol.

1-(4-Chloro-2-methylphenyl)-4-(pyrrolidin-1-yl)-1H-pyrazolo[3,4-d]pyrimidine (C16H16ClN5) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, chlorine substitution. Halogen substitution raises its density and boiling point; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
