Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 1,2-Bis(4-fluorophenyl)ethane.
CATO supplies 1,2-Bis(4-fluorophenyl)ethane (CAS 458-76-4), a certified reference material (molecular formula C14H12F2, MW 218.24 g/mol) for analytical method development and quality control.
Owing to fluorine substitution, a polycyclic aromatic system, 1,2-Bis(4-fluorophenyl)ethane is typically pale yellow to yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 218.24 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), 1,2-Bis(4-fluorophenyl)ethane 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.
