Chemical Structure
Description
The molecular framework of 5-(Ethylamino)-6-methylpyrazine-2,3-dicarbonitrile (C9H9N5) is characterized by a nitrogen-containing heterocyclic scaffold, a nitrile group. 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).
5-(Ethylamino)-6-methylpyrazine-2,3-dicarbonitrile (CAS 72112-35-7), molecular formula C9H9N5 and molecular weight 187.20 g/mol, is a CATO reference standard with documented purity and traceability.
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), 5-(Ethylamino)-6-methylpyrazine-2,3-dicarbonitrile 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.
