Chemical Structure
Description
The occurrence of 1,1-Difluoro-2-isothiocyanatoethane is closely related to a nitrile group, sulfur-containing functionality, fluorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies 1,1-Difluoro-2-isothiocyanatoethane (CAS 675-37-6), a certified reference material (molecular formula C3H3F2NS, MW 123.12 g/mol) for analytical method development and quality control.
1,1-Difluoro-2-isothiocyanatoethane (C3H3F2NS) contains a nitrile group, sulfur-containing functionality, fluorine substitution. 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.
