Chemical Structure
Description
Owing to a flavonoid core, a sulfone group, a hydroxyl group, an ether linkage, (4,4-(cyclopent-1-ene-1,2-diyl)bis(5-methylthiophene-4,2-diyl))diboronic acid is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 348.05 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).
(4,4-(cyclopent-1-ene-1,2-diyl)bis(5-methylthiophene-4,2-diyl))diboronic acid (CAS 608528-48-9), molecular formula C15H18B2O4S2 and molecular weight 348.05 g/mol, is a CATO reference standard with documented purity and traceability.
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), (4,4-(cyclopent-1-ene-1,2-diyl)bis(5-methylthiophene-4,2-diyl))diboronic acid 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.
