Tert-Butyl (9-aminononyl) carbamate

Tert-Butyl (9-aminononyl) carbamate is an alkane chain featuring a terminal amine and a Boc-protected amino group. It serves as a PROTAC linker in the synthesis of PROTACs and various coupling applications. The amine can react with carboxylic acids, activated NHS esters, and carbonyl groups (ketones, aldehydes) . The Boc group can be deprotected under mild acidic conditions to form a free amine.
