Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 4-Butyl-4'-((4-ethyl-2,6-difluorophenyl)ethynyl)-1,1'-biphenyl.
CATO supplies 4-Butyl-4'-((4-ethyl-2,6-difluorophenyl)ethynyl)-1,1'-biphenyl (CAS 1262860-96-7), a certified reference material (molecular formula C26H24F2, MW 374.47 g/mol) for analytical method development and quality control.
4-Butyl-4'-((4-ethyl-2,6-difluorophenyl)ethynyl)-1,1'-biphenyl (C26H24F2) contains fluorine 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-Butyl-4'-((4-ethyl-2,6-difluorophenyl)ethynyl)-1,1'-biphenyl 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.
