Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 4,4'-Dinitro-3,3'-bis(trifluoromethyl)biphenyl.
CATO supplies 4,4'-Dinitro-3,3'-bis(trifluoromethyl)biphenyl (CAS 363-95-1), a certified reference material (molecular formula C14H6F6N2O4, MW 380.20 g/mol) for analytical method development and quality control.
Based on its molecular formula C14H6F6N2O4, 4,4'-Dinitro-3,3'-bis(trifluoromethyl)biphenyl contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 380.20 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.
As a certified reference material (CRM), 4,4'-Dinitro-3,3'-bis(trifluoromethyl)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.
