Pentaerythritol tetrakis(2-mercaptoacetate)（Cat No.:M121311） is a complex compound commonly known as thiolated pentaerythritol. It is synthesized by reacting pentaerythritol with mercaptoacetic acid. This compound is valued for its ability to form self-assembled monolayers (SAMs) on gold surfaces, which have applications in nanotechnology, surface science, and biosensors. Thiolated pentaerythritol’s unique structure allows it to bind strongly to gold surfaces through the thiol groups, forming stable monolayers. These monolayers can be further modified to introduce specific functionalities, making thiolated pentaerythritol a versatile compound for surface modification and nanotechnology applications.
