Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Ethyl 2-cyano-3-methylhept-4-ynoate.
Ethyl 2-cyano-3-methylhept-4-ynoate (CAS 61791-94-4), molecular formula C12H13NO5 and molecular weight 251.24 g/mol, is a CATO reference standard with documented purity and traceability.
Ethyl 2-cyano-3-methylhept-4-ynoate (C12H13NO5) 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.
As a certified reference material (CRM), Ethyl 2-cyano-3-methylhept-4-ynoate 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.
