Chemical Structure
Description
The occurrence of 4,4,5,5-Tetramethyl-2-(m-tolyl)-1,3,2-dioxaborolane-d3 is closely related to deuterium isotope labeling, 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-(m-tolyl)-1,3,2-dioxaborolane-d3 (CAS 1592865-91-2) is a high-purity analytical reference standard with the molecular formula C13H16D3BO2 and a molecular weight of 221.12 g/mol.
4,4,5,5-Tetramethyl-2-(m-tolyl)-1,3,2-dioxaborolane-d3 (C13H16D3BO2) contains deuterium isotope labeling, a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system. Its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
