4-(4-Chloro-3-isopropyl-1H-pyrazolo[3,4-b]pyridin-1-yl)-3-ethylbenzonitrile CAS 2306262-57-5

Description

As a certified reference material (CRM), 4-(4-Chloro-3-isopropyl-1H-pyrazolo[3,4-b]pyridin-1-yl)-3-ethylbenzonitrile 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.

4-(4-Chloro-3-isopropyl-1H-pyrazolo[3,4-b]pyridin-1-yl)-3-ethylbenzonitrile (CAS 2306262-57-5) is a high-purity analytical reference standard with the molecular formula C18H17ClN4 and a molecular weight of 324.81 g/mol.

The molecular framework of 4-(4-Chloro-3-isopropyl-1H-pyrazolo[3,4-b]pyridin-1-yl)-3-ethylbenzonitrile (C18H17ClN4) 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.
