Chemical Structure
Description
As a certified reference material (CRM), 2-((4-Fluorobenzyl)amino)-1,1-bis(4-fluorophenyl)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.
2-((4-Fluorobenzyl)amino)-1,1-bis(4-fluorophenyl)ethanol (CAS 338771-08-7) is a high-purity analytical reference standard with the molecular formula C21H18F3NO and a molecular weight of 357.37 g/mol.
2-((4-Fluorobenzyl)amino)-1,1-bis(4-fluorophenyl)ethanol (C21H18F3NO) contains a steroid core, an amide group, 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; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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.
