3-bromo-1H-pyrazolo[3,4-b]pyridin-5-amine CAS 1186608-71-8

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 3-bromo-1H-pyrazolo[3,4-b]pyridin-5-amine.

3-bromo-1H-pyrazolo[3,4-b]pyridin-5-amine (CAS 1186608-71-8), molecular formula C6H13BrN4 and molecular weight 221.10 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a nitrile group, bromine substitution, 3-bromo-1H-pyrazolo[3,4-b]pyridin-5-amine is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 221.10 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

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.
