Chemical Structure

3-(4,4,5,5-Tetramethyl-1,3,2-dioxaborolan-2-yl)-6-benzofuranol 6-acetate CAS 905971-68-8 chemical structure

Description

The occurrence of 3-(4,4,5,5-Tetramethyl-1,3,2-dioxaborolan-2-yl)-6-benzofuranol 6-acetate is closely related to a flavonoid core, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

3-(4,4,5,5-Tetramethyl-1,3,2-dioxaborolan-2-yl)-6-benzofuranol 6-acetate (CAS 905971-68-8) is a high-purity analytical reference standard with the molecular formula C16H19BO5 and a molecular weight of 302.13 g/mol.

The molecular framework of 3-(4,4,5,5-Tetramethyl-1,3,2-dioxaborolan-2-yl)-6-benzofuranol 6-acetate (C16H19BO5) is characterized by a flavonoid core, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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), 3-(4,4,5,5-Tetramethyl-1,3,2-dioxaborolan-2-yl)-6-benzofuranol 6-acetate 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.
