2-((4-Chlorophenyl)thio)-5-nitrobenzonitrile CAS 78940-73-5

Description

The occurrence of 2-((4-Chlorophenyl)thio)-5-nitrobenzonitrile is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

2-((4-Chlorophenyl)thio)-5-nitrobenzonitrile (CAS 78940-73-5), molecular formula C13H7ClN2O2S and molecular weight 290.72 g/mol, is a CATO reference standard with documented purity and traceability.

Based on its molecular formula C13H7ClN2O2S, 2-((4-Chlorophenyl)thio)-5-nitrobenzonitrile contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 290.72 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.
