Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
2-(4-Fluorostyryl)-4,4,5,5-tetramethyl-1,3,2-dioxaborolane (CAS 1332499-06-5), molecular formula C14H18BFO2 and molecular weight 248.10 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution, an aromatic ring system, 2-(4-Fluorostyryl)-4,4,5,5-tetramethyl-1,3,2-dioxaborolane is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 248.10 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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-Fluorostyryl)-4,4,5,5-tetramethyl-1,3,2-dioxaborolane 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.
