Chemical Structure
Description
The occurrence of 4,4,5,5-Tetramethyl-2-(5,6,7,8-tetrahydronaphthalen-1-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.
CATO supplies 4,4,5,5-Tetramethyl-2-(5,6,7,8-tetrahydronaphthalen-1-yl)-1,3,2-dioxaborolane (CAS 929031-44-7), a certified reference material (molecular formula C16H23BO2, MW 258.16 g/mol) for analytical method development and quality control.
The molecular framework of 4,4,5,5-Tetramethyl-2-(5,6,7,8-tetrahydronaphthalen-1-yl)-1,3,2-dioxaborolane (C16H23BO2) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), 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.
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.
