Chemical Structure
Description
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.
2-(2,3-Dihydrobenzofuran-5-yl)ethyl 4-methylbenzenesulfonate (CAS 79679-49-5) is a high-purity analytical reference standard with the molecular formula C17H18O4S and a molecular weight of 318.39 g/mol.
The molecular framework of 2-(2,3-Dihydrobenzofuran-5-yl)ethyl 4-methylbenzenesulfonate (C17H18O4S) is characterized by a flavonoid core, a sulfone group, a hydroxyl group, an ether linkage. 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 high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
As a certified reference material (CRM), 2-(2,3-Dihydrobenzofuran-5-yl)ethyl 4-methylbenzenesulfonate 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.
