Chemical Structure
Description
2,3',5'-Trifluoro-[1,1'-biphenyl]-4-carbaldehyde (CAS 1318975-41-5) is a high-purity analytical reference standard with the molecular formula C13H7F3O and a molecular weight of 236.19 g/mol.
The molecular framework of 2,3',5'-Trifluoro-[1,1'-biphenyl]-4-carbaldehyde (C13H7F3O) is characterized by a hydroxyl group, an ether linkage, fluorine substitution, an aromatic ring system. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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), 2,3',5'-Trifluoro-[1,1'-biphenyl]-4-carbaldehyde 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.
