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 2-(4-((2-Fluorobenzyl)oxy)-3-methylphenyl)-4,4,5,5-tetramethyl-1,3,2-dioxaborolane (CAS 2096995-98-9), a certified reference material (molecular formula C20H24BFO3, MW 342.21 g/mol) for analytical method development and quality control.
2-(4-((2-Fluorobenzyl)oxy)-3-methylphenyl)-4,4,5,5-tetramethyl-1,3,2-dioxaborolane (C20H24BFO3) contains a steroid core, a hydroxyl group, an ether linkage, fluorine substitution. Halogen substitution raises its density and boiling point, 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).
As a certified reference material (CRM), 2-(4-((2-Fluorobenzyl)oxy)-3-methylphenyl)-4,4,5,5-tetramethyl-1,3,2-dioxaborolane meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
