2-(4-((Ethylthio)methyl)phenyl)-4,4,5,5-tetramethyl-1,3,2-dioxaborolane CAS 1256359-06-4

Description

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.

CATO supplies 2-(4-((Ethylthio)methyl)phenyl)-4,4,5,5-tetramethyl-1,3,2-dioxaborolane (CAS 1256359-06-4), a certified reference material (molecular formula C15H23BO2S, MW 278.22 g/mol) for analytical method development and quality control.

2-(4-((Ethylthio)methyl)phenyl)-4,4,5,5-tetramethyl-1,3,2-dioxaborolane (C15H23BO2S) contains a sulfone group, 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 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).

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.
