Chemical Structure
Description
CATO supplies 4,4,5,5-Tetramethyl-2-(4-(methylsulfinyl)phenyl)-1,3,2-dioxaborolane (CAS 1016641-70-5), a certified reference material (molecular formula C13H19BO3S, MW 266.16 g/mol) for analytical method development and quality control.
4,4,5,5-Tetramethyl-2-(4-(methylsulfinyl)phenyl)-1,3,2-dioxaborolane (C13H19BO3S) contains a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system. It is notably hygroscopic, 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).
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
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.
