7-Oxo-4,7-dihydro-1H-pyrazolo[4,3-b]pyridine-6-carbonitrile CAS 59376-27-1

Description

The occurrence of 7-Oxo-4,7-dihydro-1H-pyrazolo[4,3-b]pyridine-6-carbonitrile is closely related to an amide group, a hydroxyl group, an ether linkage, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

7-Oxo-4,7-dihydro-1H-pyrazolo[4,3-b]pyridine-6-carbonitrile (CAS 59376-27-1) is a high-purity analytical reference standard with the molecular formula C7H4N4O and a molecular weight of 160.13 g/mol.

The molecular framework of 7-Oxo-4,7-dihydro-1H-pyrazolo[4,3-b]pyridine-6-carbonitrile (C7H4N4O) is characterized by an amide group, a hydroxyl group, an ether linkage, an aromatic ring system. 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 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.
