I. [Product Description]
Biotin-PEG-VA is a multifunctional organic intermediate formed by covalently linking biotin and valeric acid (VA) via a polyethylene glycol (PEG) chain. It combines the high affinity of biotin with the excellent water solubility and biocompatibility of PEG. This compound can be used as a pharmaceutical intermediate or catalyst carrier and is widely applied in the fields of bioconjugation, material surface modification, and functional polymer synthesis. The molecular weight can be custom-designed to meet different experimental needs.

II. [Product Details]
