| Heterobifunctional PEG Derivatives Heterobifunctional PEG derivatives are useful as cross-linking agents or as spacers between two different entities. The PEG moiety in the heterobifunctional PEG derivatives provides water solutility, biocompatibility, and flexibility. Heterobifunctional PEG derivatives have the following general structure: X - PEG - Y where X and Y are two different functional groups or active groups HO-PEG-COOH: Hydroxyl PEG Carboxyl, MW 2000, MW 3500, MW 5000, MW 7500 These PEG derivatives also called PEG mono acids. JenKem's PEG mono acids are chromatographically purified with a purity of 95% or greater.  | Item Number | Price for 1.0g | Price for 5.0g | | HO-PEG2000-COOH | $200 | $800 | HO-PEG3500-COOH | $200 | $800 | HO-PEG5000-COOH | $200 | $800 | HO-PEG7500-COOH | $200 | $800 |
