Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 2,2'-Bis(trifluoromethanesulfonyloxy)-1,1'-biphenyl.
CATO supplies 2,2'-Bis(trifluoromethanesulfonyloxy)-1,1'-biphenyl (CAS 17763-95-0), a certified reference material (molecular formula C14H8F6O6S2, MW 450.33 g/mol) for analytical method development and quality control.
Structurally, 2,2'-Bis(trifluoromethanesulfonyloxy)-1,1'-biphenyl (C14H8F6O6S2) contains a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution, a polycyclic aromatic system. The molecule exhibits a degree of unsaturation (DBE) of 8.0, corresponding to approximately 8 ring(s) or double-bond equivalent(s). With a molecular weight of 450.33 g/mol, it falls into the moderately-high-molecular-weight range. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
