Chemical Structure
Description
The occurrence of 1-Fluoro-2-methoxy-4-(methylsulfanyl)benzene is closely related to sulfur-containing functionality, 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.
CATO supplies 1-Fluoro-2-methoxy-4-(methylsulfanyl)benzene (CAS 1822763-67-6), a certified reference material (molecular formula C8H9FOS, MW 172.22 g/mol) for analytical method development and quality control.
1-Fluoro-2-methoxy-4-(methylsulfanyl)benzene (C8H9FOS) contains sulfur-containing functionality, a hydroxyl group, an ether linkage, fluorine substitution, an aromatic ring system. Halogen substitution raises its density and boiling point; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
