Application

Polyethylene glycols (PEGs) are FDA approved hydrophilic polymers. They are non-toxic, non-immunogenic and non-antigenic, and are widely used in a varity of biomedical applications such as bioconjugation, drug delivery, surface functionalization, and tissue engineering. Methoxy PEG Hydrazide reacts with aldehydes and ketones to give stable hydrazones in a single step; it can also react with activated carboxylic acids.
