Chemical Structure
Description
(4-Fluoro-2-isobutoxyphenyl)(methyl)sulfane (CAS 1443355-74-5) is a high-purity analytical reference standard with the molecular formula C11H15FOS and a molecular weight of 214.30 g/mol.
The molecular framework of (4-Fluoro-2-isobutoxyphenyl)(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. 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.
As a certified reference material (CRM), (4-Fluoro-2-isobutoxyphenyl)(methyl)sulfane meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
