methyl 3-bromo-1H-pyrazolo[4,3-b]pyridine-6-carboxylate (CAS 1352398-55-0) is a high-purity analytical reference standard with the molecular formula C8H14BrN3O2 and a molecular weight of 264.12 g/mol.

Structurally, methyl 3-bromo-1H-pyrazolo[4,3-b]pyridine-6-carboxylate (C8H14BrN3O2) contains an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, bromine substitution. The molecule exhibits a degree of unsaturation (DBE) of 3.0, corresponding to approximately 3 ring(s) or double-bond equivalent(s). With a molecular weight of 264.12 g/mol, it falls into the medium-molecular-weight range. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

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.
