Description
As a certified reference material (CRM), 5'-Fluoro-2'-hydroxy-4-methoxychalcone 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.
CATO supplies 5'-Fluoro-2'-hydroxy-4-methoxychalcone (CAS 391-94-6), a certified reference material (molecular formula C16H13FO3, MW 272.27 g/mol) for analytical method development and quality control.
Structurally, 5'-Fluoro-2'-hydroxy-4-methoxychalcone (C16H13FO3) contains a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution, a polycyclic aromatic system. The molecule exhibits a degree of unsaturation (DBE) of 10.0, corresponding to approximately 10 ring(s) or double-bond equivalent(s). With a molecular weight of 272.27 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.
