PEG Derivatives by Structure


Numerous scientific articles have reported the various applications of polyethylene glycol (PEG) derivatives. PEG usually can be functionalized by combining with other compounds through terminal functional groups. PEG and its detivatives have been widely used in chemical, biological, medical, industral and commercial fields. Taking the utilizaiton of these materials in medical and pharmaceutical fields as an example, their applications in a variety of research and development areas are expanding, such as medical devices, drug development, and diagnostics areas. PEG derivaties have been widely used in drug delivery, wound healing, cell culture models and tissue regeneration.

BOC Sciences provides our customers with a variety of PEG derivatives with low polydispersity, high reactivity and high purity. We have structurally diversified derivatives, including linear, branched and multi-arm PEGs, and functionally diversified derivatives containing multiple kinds of reactive groups, such as NH2, COOH, OH, SH, DSPE, OPSS, Fmoc, Boc, etc. Our products also include biotin and fluorescent labeled PEG derivatives.

BOC Sciences’ products are easy to order and fast arrival. Our products with stable and high quality can meet all your needs from scientific research to commercial applications. The available PEG derivatives in BOC Sciences include methoxy liner PEG (mPEG), monodisperse PEG, homobifunctional PEG, heterobifunctional PEG, multi-arm PEG, lipid PEG, fluorescent PEG, biotin PEG and group protected PEG.
