4-Bromo-1,6-dimethyl-1,6-dihydro-7H-pyrazolo[3,4-c]pyridin-7-one CAS 1782578-99-7

Description

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.

4-Bromo-1,6-dimethyl-1,6-dihydro-7H-pyrazolo[3,4-c]pyridin-7-one (CAS 1782578-99-7), molecular formula C8H8BrN3O and molecular weight 242.07 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, bromine substitution, 4-Bromo-1,6-dimethyl-1,6-dihydro-7H-pyrazolo[3,4-c]pyridin-7-one is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 242.07 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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.
