SH-PEG6-COOH (CAS: 1347750-77-9, Thiol-PEG6-acid) is a bifunctional PEG derivative with a reactive thiol group on one end and a carboxylic acid group on the other. This structure allows for the formation of stable hydrophilic conjugates through thiol-disulfide exchange or thiol-maleimide click chemistry. 

SH-PEG6-COOH is widely used in pharmaceutical research to create PEGylated bioconjugates for targeted drug delivery and controlled release. Its functional groups facilitate conjugation with proteins, peptides, and other bioactive molecules, improving their pharmacokinetic properties, reducing immunogenicity, and enhancing therapeutic efficacy across various clinical applications.
