Description

Compared with other compounds in its class, the molecular weight of 252.07 g/mol gives 1H-Pyrazolo[4,3-d]pyrimidine-3-carbonitrile, 7-bromo-5-ethyl- distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

1H-Pyrazolo[4,3-d]pyrimidine-3-carbonitrile, 7-bromo-5-ethyl- (CAS 2091698-72-3) is a high-purity analytical reference standard with the molecular formula C8H6BrN5 and a molecular weight of 252.07 g/mol.

Owing to a nitrogen-containing heterocyclic scaffold, a nitrile group, bromine substitution, 1H-Pyrazolo[4,3-d]pyrimidine-3-carbonitrile, 7-bromo-5-ethyl- is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 252.07 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.

As a certified reference material (CRM), 1H-Pyrazolo[4,3-d]pyrimidine-3-carbonitrile, 7-bromo-5-ethyl- meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
