Chemical Structure

5-Bromo-1-(3-chlorophenyl)-3-methyl-1h-pyrazolo[3,4-b]pyridine CAS 1019125-50-8 chemical structure

Description

The occurrence of 5-Bromo-1-(3-chlorophenyl)-3-methyl-1h-pyrazolo[3,4-b]pyridine is closely related to a nitrogen-containing heterocyclic scaffold, a nitrile group, chlorine/bromine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies 5-Bromo-1-(3-chlorophenyl)-3-methyl-1h-pyrazolo[3,4-b]pyridine (CAS 1019125-50-8), a certified reference material (molecular formula C13H9BrClN3, MW 322.59 g/mol) for analytical method development and quality control.

The molecular framework of 5-Bromo-1-(3-chlorophenyl)-3-methyl-1h-pyrazolo[3,4-b]pyridine (C13H9BrClN3) is characterized by a nitrogen-containing heterocyclic scaffold, a nitrile group, chlorine/bromine 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).

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.
