Chemical Structure
Description
As a certified reference material (CRM), Ethyl (2e)-2-cyano-3-[(pyrazin-2-yl)amino]prop-2-enoate 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.
Ethyl (2e)-2-cyano-3-[(pyrazin-2-yl)amino]prop-2-enoate (CAS 871926-02-2), molecular formula C10H10N4O2 and molecular weight 218.21 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of Ethyl (2e)-2-cyano-3-[(pyrazin-2-yl)amino]prop-2-enoate (C10H10N4O2) is characterized by an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage. 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).
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.
