Chemical Structure

3-(2-Chlorophenyl)-2,5-dimethyl-7-(piperidin-1-yl)pyrazolo[1,5-a]pyrimidine CAS 890632-38-9 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 3-(2-Chlorophenyl)-2,5-dimethyl-7-(piperidin-1-yl)pyrazolo[1,5-a]pyrimidine.

3-(2-Chlorophenyl)-2,5-dimethyl-7-(piperidin-1-yl)pyrazolo[1,5-a]pyrimidine (CAS 890632-38-9) is a high-purity analytical reference standard with the molecular formula C19H21ClN4 and a molecular weight of 340.85 g/mol.

The molecular framework of 3-(2-Chlorophenyl)-2,5-dimethyl-7-(piperidin-1-yl)pyrazolo[1,5-a]pyrimidine (C19H21ClN4) is characterized by a nitrogen-containing heterocyclic scaffold, a nitrile group, chlorine substitution. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.

As a certified reference material (CRM), 3-(2-Chlorophenyl)-2,5-dimethyl-7-(piperidin-1-yl)pyrazolo[1,5-a]pyrimidine meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
