Chemical Structure

1-Methyl-1H-pyrazolo[3,4-b]pyridine CAS 23002-49-5 chemical structure

Description

The occurrence of 1-Methyl-1H-pyrazolo[3,4-b]pyridine is closely related to a nitrile group, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies 1-Methyl-1H-pyrazolo[3,4-b]pyridine (CAS 23002-49-5), a certified reference material (molecular formula C7H7N3, MW 133.15 g/mol) for analytical method development and quality control.

The molecular framework of 1-Methyl-1H-pyrazolo[3,4-b]pyridine (C7H7N3) is characterized by a nitrile group, 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).

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.
