Chemical Structure
Description
1-Bromo-2-thiocyanatobenzene (C7H4BrNS) contains a nitrile group, sulfur-containing functionality, bromine 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.
1-Bromo-2-thiocyanatobenzene (CAS 55757-32-9), molecular formula C7H4BrNS and molecular weight 214.08 g/mol, is a CATO reference standard with documented purity and traceability.
