1,4-Dichloro-2-[(2-chloroethyl)sulfanyl]benzene CAS 742104-71-8

Description

Compared with other compounds in its class, the molecular weight of 241.57 g/mol gives 1,4-Dichloro-2-[(2-chloroethyl)sulfanyl]benzene distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

1,4-Dichloro-2-[(2-chloroethyl)sulfanyl]benzene (CAS 742104-71-8) is a high-purity analytical reference standard with the molecular formula C8H7Cl3S and a molecular weight of 241.57 g/mol.

1,4-Dichloro-2-[(2-chloroethyl)sulfanyl]benzene (C8H7Cl3S) contains sulfur-containing functionality, chlorine substitution, an aromatic ring system. Halogen substitution raises its density and boiling point; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
