Chemical Structure
Description
The occurrence of 5-Chloro-1H-pyrrole-2-carbonitrile is closely related to a nitrile group, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
5-Chloro-1H-pyrrole-2-carbonitrile (CAS 827342-90-5), molecular formula C5H3ClN2 and molecular weight 126.54 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a nitrile group, chlorine substitution, 5-Chloro-1H-pyrrole-2-carbonitrile is typically off-white to pale yellow liquid. Its solid-state physicochemical attributes — including a molecular weight of 126.54 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).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
