Description
CATO supplies 2-(2-((4-Bromophenoxy)methyl)phenyl)-4,4,5,5-tetramethyl-1,3,2-dioxaborolane (CAS 2246758-17-6), a certified reference material (molecular formula C19H22BBrO3, MW 389.09 g/mol) for analytical method development and quality control.
Owing to a steroid core, a hydroxyl group, an ether linkage, bromine substitution, 2-(2-((4-Bromophenoxy)methyl)phenyl)-4,4,5,5-tetramethyl-1,3,2-dioxaborolane is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 389.09 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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.
As a certified reference material (CRM), 2-(2-((4-Bromophenoxy)methyl)phenyl)-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.
