Properties

Description

Methylamino-PEG2-t-butyl ester is a PEG linker with a methylamino group and a t-butyl-protected ester. The methylamine group allows for efficient reactivity with carboxylic acids and carbonyl compounds, while the t-butyl ester provides acid-labile protection for controlled carboxylic acid activation. The PEG2 spacer enhances water solubility and hydrophilicity.
