(4-Ethoxy-3,5-difluorophenyl)(methyl)sulfane CAS 1379368-66-7

Description

The occurrence of (4-Ethoxy-3,5-difluorophenyl)(methyl)sulfane 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.

(4-Ethoxy-3,5-difluorophenyl)(methyl)sulfane (CAS 1379368-66-7), molecular formula C9H10F2OS and molecular weight 204.24 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of (4-Ethoxy-3,5-difluorophenyl)(methyl)sulfane (C9H10F2OS) 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 the polarity and ionization state of its functional groups, 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.

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.
