4,4,5,5-Tetramethyl-2-(4-methyl-2,3-dihydrobenzofuran-5-yl)-1,3,2-dioxaborolane CAS 1154740-64-3

Description

The occurrence of 4,4,5,5-Tetramethyl-2-(4-methyl-2,3-dihydrobenzofuran-5-yl)-1,3,2-dioxaborolane is closely related to a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

4,4,5,5-Tetramethyl-2-(4-methyl-2,3-dihydrobenzofuran-5-yl)-1,3,2-dioxaborolane (CAS 1154740-64-3) is a high-purity analytical reference standard with the molecular formula C15H21BO3 and a molecular weight of 260.14 g/mol.

Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system, 4,4,5,5-Tetramethyl-2-(4-methyl-2,3-dihydrobenzofuran-5-yl)-1,3,2-dioxaborolane is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 260.14 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
