The occurrence of [(4-Phenoxybutyl)sulfanyl]benzene is closely related to sulfur-containing functionality, a hydroxyl group, an ether linkage, a polycyclic aromatic system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
[(4-Phenoxybutyl)sulfanyl]benzene (CAS 59950-11-7) is a high-purity analytical reference standard with the molecular formula C16H18OS and a molecular weight of 258.38 g/mol.
Owing to sulfur-containing functionality, a hydroxyl group, an ether linkage, a polycyclic aromatic system, [(4-Phenoxybutyl)sulfanyl]benzene is typically pale yellow to yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 258.38 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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-Phenoxybutyl)sulfanyl]benzene 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.
