Chemical Structure
Description
The occurrence of 2-(5-Chloropyrazin-2-yl)acetonitrile is closely related to a nitrile group, chlorine substitution, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies 2-(5-Chloropyrazin-2-yl)acetonitrile (CAS 1433707-71-1), a certified reference material (molecular formula C6H4ClN3, MW 153.57 g/mol) for analytical method development and quality control.
The molecular framework of 2-(5-Chloropyrazin-2-yl)acetonitrile (C6H4ClN3) is characterized by a nitrile group, chlorine substitution, an aromatic ring system. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
As a certified reference material (CRM), 2-(5-Chloropyrazin-2-yl)acetonitrile 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.
