Used as an intermediate in organic synthesis, particularly in the preparation of pharmaceuticals and functionalized polymers. Its ester and amine functional groups allow for versatile chemical modifications, making it valuable in the development of drug delivery systems and bioactive molecules. Commonly employed in conjugation reactions where a spacer with both hydrophobic and hydrophilic characteristics is required. Also utilized in the synthesis of fluorescent probes and labeled compounds due to its reactive amine group that can be easily acylated or alkylated.
