Chemical Structure
Description
Owing to a nitrile group, bromine substitution, 1-amino-4-bromo-1H-pyrrole-2-carbonitrile is typically white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 190.04 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).
1-amino-4-bromo-1H-pyrrole-2-carbonitrile (CAS 937161-86-9) is a high-purity analytical reference standard with the molecular formula C5H8BrN3 and a molecular weight of 190.04 g/mol.
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.
