NH-bis (PEG8-OH)

NH-bis (PEG8-OH) is a bifunctional reagent comprising two alcohol groups linked by a secondary amine. The alcohol groups can react with carboxylic acids to form esters, while the secondary amine serves as a nucleophile, allowing it to connect with ketones, aldehydes, and carboxylic acids. The PEG spacer confers water solubility, potentially altering the molecule's DMPK properties.
