Description
This compound incorporates a PEG14 chain, an acid group, and a t-butyl ester. The long PEG14 chain offers significant improvements in solubility and can impart stealth properties to associated molecules. The acid group provides the potential for chemical reactions and modifications, while the t-butyl ester serves as a protecting group that can be selectively removed under appropriate conditions. This protection and reactivity combination makes it a useful intermediate in organic synthesis and the preparation of complex molecules.
