mPEG-C6-Hydrazine (cleavable)

mPEG-C6-Hydrazine features a monomethoxy polyethylene glycol chain connected to a hydrazine terminus through a six‑carbon alkyl spacer. The hydrazine group in mPEG-C6-Hydrazine enables specific conjugation with aldehydes or ketones to form hydrazone linkages. mPEG-C6-Hydrazine is widely used for pH‑sensitive bioconjugation, glycoprotein labeling, and the construction of stimulus‑responsive therapeutic or diagnostic agents.
