Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 6-Bromo-1-methyl-1H-pyrazolo[4,3-b]pyridin-3-amine.
6-Bromo-1-methyl-1H-pyrazolo[4,3-b]pyridin-3-amine (CAS 2007915-41-3), molecular formula C7H7BrN4 and molecular weight 227.06 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, 6-Bromo-1-methyl-1H-pyrazolo[4,3-b]pyridin-3-amine (C7H7BrN4) contains a nitrile group, bromine substitution, an aromatic ring system. The molecule exhibits a degree of unsaturation (DBE) of 6.0, corresponding to approximately 6 ring(s) or double-bond equivalent(s). With a molecular weight of 227.06 g/mol, it falls into the medium-molecular-weight range. 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.
