4arm PEG Amine, HCl Salt
$50.00 – $2,400.00
4arm PEG Amine, HCl Salt, reagent with superior quality specification of ≥ 95% Substitution.
JenKem Technology’s 4arm PEG Amine derivatives can be cross-linked into PEG hydrogels. The HCl salt provides stability to the solid form of 4arm amine PEG. PEG hydrogels have a variety of applications in medical devices and regenerative medicine, and are especially of interest for controlled release of drugs, for 2D and 3D cell culture, and for wound sealing and healing. JenKem Technology’s 4arm PEGs are synthesized by ethoxylation of pentaerythritol. The number of ethylene oxide units in the PEG chain may not be equal for all arms. The total molecular weight reported for the JenKem multi-arm PEGs is the sum of the PEG molecular weights of each arm.
4arm NH2 star PEG products with molecular weights, branching, and functional groups not listed in our online catalog may be available by custom synthesis. Please inquire at email@example.com about pricing and availability.
Bulk PEGs and GMP grade PEGs are made-to-order. Please contact us for bulk pricing.
