Chemical Structure
Description
As a certified reference material (CRM), 2-((4-Chlorobenzyl)amino)-1,1-bis(4-chlorophenyl)ethanol 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.
CATO supplies 2-((4-Chlorobenzyl)amino)-1,1-bis(4-chlorophenyl)ethanol (CAS 321432-78-4), a certified reference material (molecular formula C21H18Cl3NO, MW 406.73 g/mol) for analytical method development and quality control.
2-((4-Chlorobenzyl)amino)-1,1-bis(4-chlorophenyl)ethanol (C21H18Cl3NO) contains a steroid core, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. 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.
