Description
CATO supplies Ethyl 2-cyano-2-(2,2-dimethyltetrahydro-4H-pyran-4-ylidene)acetate (CAS 64792-49-0), a certified reference material (molecular formula C12H17NO3, MW 223.27 g/mol) for analytical method development and quality control.
The molecular framework of Ethyl 2-cyano-2-(2,2-dimethyltetrahydro-4H-pyran-4-ylidene)acetate (C12H17NO3) 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 its high hydrophobicity (logP), 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).
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-2-(2,2-dimethyltetrahydro-4H-pyran-4-ylidene)acetate 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.
