4,4,5,5-Tetramethyl-2-(4-(4-((tetrahydro-2H-pyran-2-yl)oxy)butoxy)-phenyl)-1,3,2-dioxaborolane CAS 1210827-89-6 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 376.29 g/mol gives 4,4,5,5-Tetramethyl-2-(4-(4-((tetrahydro-2H-pyran-2-yl)oxy)butoxy)-phenyl)-1,3,2-dioxaborolane distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies 4,4,5,5-Tetramethyl-2-(4-(4-((tetrahydro-2H-pyran-2-yl)oxy)butoxy)-phenyl)-1,3,2-dioxaborolane (CAS 1210827-89-6), a certified reference material (molecular formula C21H33BO5, MW 376.29 g/mol) for analytical method development and quality control.

Owing to a steroid core, a hydroxyl group, an ether linkage, 4,4,5,5-Tetramethyl-2-(4-(4-((tetrahydro-2H-pyran-2-yl)oxy)butoxy)-phenyl)-1,3,2-dioxaborolane is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 376.29 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).

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
