Chemical Structure
Description
As a certified reference material (CRM), 2-Cyano-3-ethoxyacrylic acid 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.
2-Cyano-3-ethoxyacrylic acid (CAS 71648-24-3) is a high-purity analytical reference standard with the molecular formula C6H7NO3 and a molecular weight of 141.12 g/mol.
2-Cyano-3-ethoxyacrylic acid (C6H7NO3) contains an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage. It is notably hygroscopic, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
