Chemical Structure
Description
The occurrence of Ethyl 2-[(3,4-dichlorophenyl)sulfanyl]acetate is closely related to a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
Ethyl 2-[(3,4-dichlorophenyl)sulfanyl]acetate (CAS 78066-06-5) is a high-purity analytical reference standard with the molecular formula C10H10Cl2O2S and a molecular weight of 265.16 g/mol.
The molecular framework of Ethyl 2-[(3,4-dichlorophenyl)sulfanyl]acetate (C10H10Cl2O2S) is characterized by a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine 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.
As a certified reference material (CRM), Ethyl 2-[(3,4-dichlorophenyl)sulfanyl]acetate 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.
