(8-chloro-7-fluoro-3-hydroxy-1-naphthyl) trifluoromethanesulfonate CAS 2621935-23-5

Description

The occurrence of (8-chloro-7-fluoro-3-hydroxy-1-naphthyl) trifluoromethanesulfonate is closely related to a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

(8-chloro-7-fluoro-3-hydroxy-1-naphthyl) trifluoromethanesulfonate (CAS 2621935-23-5) is a high-purity analytical reference standard with the molecular formula C11H15ClF4O4S and a molecular weight of 354.75 g/mol.

The molecular framework of (8-chloro-7-fluoro-3-hydroxy-1-naphthyl) trifluoromethanesulfonate (C11H15ClF4O4S) is characterized by a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine/chlorine 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 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.

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.
