Chemical Structure
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-(4-neopentylphenyl)-1,3,2-dioxaborolane (CAS 2648451-28-7), a certified reference material (molecular formula C17H27BO2, MW 274.21 g/mol) for analytical method development and quality control.
4,4,5,5-Tetramethyl-2-(4-neopentylphenyl)-1,3,2-dioxaborolane (C17H27BO2) contains a steroid core, a hydroxyl group, an ether linkage. 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).
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.
