Chemical Structure
Description
CATO supplies Ethyl (E)-2-cyano-2-(2-(2,6-difluorophenyl)hydrazono)acetate (CAS 478048-48-5), a certified reference material (molecular formula C11H9F2N3O2, MW 253.20 g/mol) for analytical method development and quality control.
Structurally, Ethyl (E)-2-cyano-2-(2-(2,6-difluorophenyl)hydrazono)acetate (C11H9F2N3O2) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 8.0, corresponding to approximately 8 ring(s) or double-bond equivalent(s). With a molecular weight of 253.20 g/mol, it falls into the medium-molecular-weight range. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
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 (E)-2-cyano-2-(2-(2,6-difluorophenyl)hydrazono)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.
