Chemical Structure

1-(4-Bromophenyl)-1H-pyrazolo[3,4-d]pyrimidin-4(5H)-one CAS 864872-05-9 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 291.10 g/mol gives 1-(4-Bromophenyl)-1H-pyrazolo[3,4-d]pyrimidin-4(5H)-one distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies 1-(4-Bromophenyl)-1H-pyrazolo[3,4-d]pyrimidin-4(5H)-one (CAS 864872-05-9), a certified reference material (molecular formula C11H7BrN4O, MW 291.10 g/mol) for analytical method development and quality control.

1-(4-Bromophenyl)-1H-pyrazolo[3,4-d]pyrimidin-4(5H)-one (C11H7BrN4O) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, bromine substitution. Halogen substitution raises its density and boiling point; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
