10-(tert-Butoxy)-10-oxodecanoic acid
10-(tert-Butoxy)-10-oxodecanoic acid is a short linker featuring a carboxylic acid and a tert-butyl ester. Carboxylic acids can be linked with alcohols or amines, while the tert-butyl ester can be selectively deprotected to allow for reactivity as a carboxylic acid to form esters or amides.
