4-Fluoro-3-(methylsulfonyl)aniline CAS 914636-44-5

Description

The occurrence of 4-Fluoro-3-(methylsulfonyl)aniline is closely related to an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

4-Fluoro-3-(methylsulfonyl)aniline (CAS 914636-44-5), molecular formula C7H8FNO2S and molecular weight 189.21 g/mol, is a CATO reference standard with documented purity and traceability.

Based on its molecular formula C7H8FNO2S, 4-Fluoro-3-(methylsulfonyl)aniline contains an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution, an aromatic ring system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 189.21 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

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.
