Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 2-Fluoro[1,1-biphenyl]-4-yl 3-(trifluoromethyl)benzenecarboxylate.
2-Fluoro[1,1-biphenyl]-4-yl 3-(trifluoromethyl)benzenecarboxylate (CAS 477857-17-3), molecular formula C20H12F4O2 and molecular weight 360.30 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 2-Fluoro[1,1-biphenyl]-4-yl 3-(trifluoromethyl)benzenecarboxylate (C20H12F4O2) is characterized by a steroid core, a hydroxyl group, an ether linkage, fluorine substitution. 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 presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
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.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
