Chemical Structure
Description
(4-Butoxy-3-fluorophenyl)(methyl)sulfane (CAS 1443340-16-6), molecular formula C11H15FOS and molecular weight 214.30 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of (4-Butoxy-3-fluorophenyl)(methyl)sulfane (C11H15FOS) is characterized by sulfur-containing functionality, a hydroxyl group, an ether linkage, fluorine substitution, an aromatic ring system. 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.
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.
