Chemical Structure
Description
CATO supplies (4-Bromophenyl)(5-chloro-2-methylphenyl)methanol (CAS 1443351-90-3), a certified reference material (molecular formula C14H12BrClO, MW 311.60 g/mol) for analytical method development and quality control.
(4-Bromophenyl)(5-chloro-2-methylphenyl)methanol (C14H12BrClO) contains a hydroxyl group, an ether linkage, chlorine/bromine substitution, a polycyclic aromatic system. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility; 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.
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), (4-Bromophenyl)(5-chloro-2-methylphenyl)methanol 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.
