3-Mercaptopropanyl-N-hydroxysuccinimide ester is an alkyl/ether-based PROTAC linker. It is used in the synthesis of PROTACs, which are molecules designed to exploit the intracellular ubiquitin-proteasome system to selectively degrade target proteins. PROTACs achieve this by connecting two different ligands: one for an E3 ubiquitin ligase and the other for the target protein.

• Alkyl/ether-based PROTAC linker
• Used in the synthesis of PROTACs
• Designed to exploit the intracellular ubiquitin-proteasome system
• Selectively degrades target proteins
