4,4,5,5-Tetramethyl-2-(3-methyl-5-propoxyphenyl)-1,3,2-dioxaborolane CAS 1218789-73-1

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 4,4,5,5-Tetramethyl-2-(3-methyl-5-propoxyphenyl)-1,3,2-dioxaborolane (CAS 1218789-73-1), a certified reference material (molecular formula C16H25BO3, MW 276.18 g/mol) for analytical method development and quality control.

4,4,5,5-Tetramethyl-2-(3-methyl-5-propoxyphenyl)-1,3,2-dioxaborolane (C16H25BO3) contains 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 high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

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.
