Properties
Description
Hydroxy-PEG9-t-butyl ester is a PEG linker featuring a terminal hydroxyl group and a t-butyl-protected carboxyl group. The PEG9 chain enhances hydrophilicity and solubility in aqueous environments. The hydroxyl group offers a versatile site for chemical modifications, while the t-butyl ester provides acid-labile protection for controlled carboxylic acid activation.
