1-FLUORO-4-(METHYLTHIO)BENZENE 1-FLUORO-4-METHYLSULFANYL-BENZENE 371-15-3 4-FLUOROPHENYL METHYL SULFIDE 4-Fluorothioanisole AS04286 P-FLUORO(METHYLTHIO)BENZENE CAS 371-15-3 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 1-FLUORO-4-(METHYLTHIO)BENZENE 1-FLUORO-4-METHYLSULFANYL-BENZENE 371-15-3 4-FLUOROPHENYL METHYL SULFIDE 4-Fluorothioanisole AS04286 P-FLUORO(METHYLTHIO)BENZENE.

CATO supplies 1-FLUORO-4-(METHYLTHIO)BENZENE 1-FLUORO-4-METHYLSULFANYL-BENZENE 371-15-3 4-FLUOROPHENYL METHYL SULFIDE 4-Fluorothioanisole AS04286 P-FLUORO(METHYLTHIO)BENZENE (CAS 371-15-3), a certified reference material (molecular formula C7H13FS, MW 148.24 g/mol) for analytical method development and quality control.

The molecular framework of 1-FLUORO-4-(METHYLTHIO)BENZENE 1-FLUORO-4-METHYLSULFANYL-BENZENE 371-15-3 4-FLUOROPHENYL METHYL SULFIDE 4-Fluorothioanisole AS04286 P-FLUORO(METHYLTHIO)BENZENE (C7H13FS) is characterized by sulfur-containing functionality, fluorine substitution. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, 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.

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.
