H2N-PEG4-tBu Chemical Properties,Usage,Production

Description

Amino-PEG4-t-butyl ester is a PEG reagent containing an amino (NH2) and a t-butyl protected carboxyl group. The hydrophilic PEG spacer increases solubility in aqueous media. The amino group is reactive with carboxylic acids, activated NHS esters, carbonyls (ketone, aldehyde) etc. The t-butyl protected carboxyl (Boc) can be deprotected under acidic conditions.

Uses

is a linker-cytotoxin conjugate. Linker-cytotoxin conjugate is related to antibody-cytotoxin and antibody-drug conjugates and related compounds.
