Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO supplies 2-(4-Fluorobenzylidene)-1-benzosuberone epoxide (CAS 325819-11-2), a certified reference material (molecular formula C18H15FO2, MW 282.31 g/mol) for analytical method development and quality control.
Structurally, 2-(4-Fluorobenzylidene)-1-benzosuberone epoxide (C18H15FO2) contains a steroid core, a hydroxyl group, an ether linkage, fluorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 11.0, corresponding to approximately 11 ring(s) or double-bond equivalent(s). With a molecular weight of 282.31 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).
As a certified reference material (CRM), 2-(4-Fluorobenzylidene)-1-benzosuberone epoxide 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.
