1-isothiocyanato-PEG3-t-butyl ester CAS:1835759-83-5 is a small molecule drug that is composed of several functional groups. The isothiocyanato group is a functional group that contains an isothiocyanate (-N=C=S) group, which is commonly used to introduce thiol-reactive groups into molecules. The PEG3 group refers to a polyethylene glycol (PEG) chain that contains three repeating units. The t-butyl ester group is a type of ester that is commonly used as a protecting group for carboxylic acids.
The combination of these functional groups in 1-isothiocyanato-PEG3-t-butyl ester is designed to create a drug that can be used to target specific biological processes in the body. The isothiocyanato group, for example, can be used to introduce thiol-reactive groups into molecules, which can help to target specific proteins or enzymes in the body. The PEG3 group can help to improve the solubility and stability of the drug in solution, while the t-butyl ester group can help to protect the carboxylic acid group from degradation or unwanted reactions.
