Description

CATO supplies (E)-2-(3,4-Dichlorobenzylidene)-6-hydroxybenzofuran-3(2h)-one (CAS 620545-98-4), a certified reference material (molecular formula C15H8Cl2O3, MW 307.13 g/mol) for analytical method development and quality control.

Structurally, (E)-2-(3,4-Dichlorobenzylidene)-6-hydroxybenzofuran-3(2h)-one (C15H8Cl2O3) contains a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, a polycyclic aromatic system. 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 307.13 g/mol, it falls into the moderately-high-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), (E)-2-(3,4-Dichlorobenzylidene)-6-hydroxybenzofuran-3(2h)-one 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.
