tert-Butyl tert-butylcarbamate is an organic compound serving as a protected derivative of tert-butylamine (N-Boc-tert-butylamine). It is used as an intermediate in organic synthesis, particularly for the preparation of carbamate-based compounds, pharmaceuticals, and fine chemicals. The Boc group provides stability during synthetic manipulations, and it can be removed under mild acidic conditions to regenerate tert-butylamine without affecting other functional groups. This makes it valuable in multi-step syntheses requiring selective deprotection.
