Chemical Structure
Description
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.
CATO supplies (7,8-difluoro-3-hydroxy-1-naphthyl) trifluoromethanesulfonate (CAS 2621935-33-7), a certified reference material (molecular formula C11H15F5O4S, MW 338.29 g/mol) for analytical method development and quality control.
The molecular framework of (7,8-difluoro-3-hydroxy-1-naphthyl) trifluoromethanesulfonate (C11H15F5O4S) is characterized by a sulfone group, a carboxylic acid group, 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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
As a certified reference material (CRM), (7,8-difluoro-3-hydroxy-1-naphthyl) trifluoromethanesulfonate 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.
