4-Chloro-2,5-difluorophenylisothiocyanate CAS 1263376-49-3

Description

The occurrence of 4-Chloro-2,5-difluorophenylisothiocyanate is closely related to a nitrile group, sulfur-containing functionality, fluorine/chlorine substitution, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

4-Chloro-2,5-difluorophenylisothiocyanate (CAS 1263376-49-3) is a high-purity analytical reference standard with the molecular formula C7H2ClF2NS and a molecular weight of 205.61 g/mol.

Based on its molecular formula C7H2ClF2NS, 4-Chloro-2,5-difluorophenylisothiocyanate contains a nitrile group, sulfur-containing functionality, fluorine/chlorine substitution, an aromatic ring system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 205.61 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.
