Description
m-PEG3-amine is a PEG reagent containing an amino group (NH2). The amino group is reactive with carboxylic acids, activated NHS esters, carbonyls (ketone, aldehyde) etc. The hydrophilic PEG spacer increases solubility in aqueous media.
Uses
m-PEG3-amine whose chemical name 2-[2-(2-methoxyethoxy)ethoxy]ethylamine,it is a PROTAC bridge, belonging to the PEG class, which can be used to synthesize a series of PROTAC molecules, and can also be used for the synthesis of antibody drug conjugates (ADCs).
Synthesis
2-[2-(2-methoxyethoxy)ethoxy]ethylamine is an organic intermediate, which can be prepared from triethylene glycol monomethyl ether as raw material to prepare 2-(2-(2-methoxyethoxy)ethoxy)ethyl 4-methylbenzenesulfonate, and then Reaction with sodium azide,and then Reacts with sodium azide to finally yield 3,6,9-trioxa-1-aminodecane.
