Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 223.12 g/mol gives 2,6-Dichlorophenylthioethanol distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
2,6-Dichlorophenylthioethanol (CAS 688762-66-5), molecular formula C8H8Cl2OS and molecular weight 223.12 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 2,6-Dichlorophenylthioethanol (C8H8Cl2OS) is characterized by sulfur-containing functionality, a hydroxyl group, an ether linkage, chlorine 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. 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.
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.
