4-bromo-3-methyl-1H-pyrazolo[3,4-c]pyridine CAS 1234616-30-8

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 4-bromo-3-methyl-1H-pyrazolo[3,4-c]pyridine.

4-bromo-3-methyl-1H-pyrazolo[3,4-c]pyridine (CAS 1234616-30-8) is a high-purity analytical reference standard with the molecular formula C7H14BrN3 and a molecular weight of 220.11 g/mol.

Owing to a nitrile group, bromine substitution, 4-bromo-3-methyl-1H-pyrazolo[3,4-c]pyridine is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 220.11 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

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.

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.
