Chemical Structure
Description
As a certified reference material (CRM), Ethyl 2-cyanohex-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 2-cyanohex-2-enoate (CAS 996-95-2), molecular formula C9H13NO2 and molecular weight 167.21 g/mol, is a CATO reference standard with documented purity and traceability.
Ethyl 2-cyanohex-2-enoate (C9H13NO2) contains an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage. The carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
