General Description

3-isocyanatobenzenesulphonyl fluoride, also known as IBFL, is a chemical compound with the molecular formula C7H4FNO3S. It is a colorless to light yellow liquid at room temperature and is highly reactive. IBFL is commonly used as an intermediate in the synthesis of pharmaceuticals and agrochemicals. It is also used as a reagent in the preparation of polypeptides and in the modification of biomolecules. IBFL is a potent electrophile due to the presence of the isocyanate group, and it is known to form covalent bonds with various nucleophiles in chemical reactions. Due to its reactivity and potential hazards, strict safety measures and handling procedures must be followed when working with 3-isocyanatobenzenesulphonyl fluoride.
