Uses:
As an intermediate in medicine and organic synthesis, it is an important amino protective agent used in the synthesis of medicine and agrochemical products.
In organic chemical reactions, tert butoxycarbonyl s reagent is often used as a substrate of amine, phenol, mercaptan, amide, lactam and carbamate a. the reaction rate is very fast and the yield is relatively high. T-butoxycarbonylation reaction (protection of functional groups); Due to the poor stability of acyl halide reagent, it is widely used as a protective group of amino group, which can be removed under acidic conditions (such as hydrochloric acid, trifluoroacetic acid s, etc.). Aliphatic amines, alicyclic amines, aromatic amines and heterocyclic amines can react with (BOC).
