The following PEG raw materials are intended for use to make PEG derivatives. They are sold without any purification after the polymerization. If you want to use PEG raw materials for dedicated research work, please contact us for research grade PEG raw materials. 


 
Linear Methoxy PEG Raw Materials

 
JenKem provides methoxy PEG raw materials as bulk order to end users in the molecular weight of 5000Da, 10000Da, 20000Da, 30000Da, and 40000Da. The methoxy PEGs are one end-capped with a methoxy group and are monofunctional.

The structure of methoxy PEG is as the following:

Multi-arm PEG Raw Materials

 
JenKem provides multi-arm PEG raw materials in bulk order to end users in various molecular weights. The total molecular weight of the multi-arm PEG is the sum of the molecular weights of all the arms.

JenKem's 4arm-PEG is prepared by ethoxylation of pentaerythritol.
JenKem's 8arm-PEG is prepared by ethoxylation of hexaglycerine or tripentaerythritol core.
 
 

JenKem now provides new 8ARM-PEG with tripentaerythritol core. The 8ARM-PEG with tripentaerythritol core have lower polydispersity and better molecular weight accuracy compared with the traditional 8ARM-PEG with hexaglycerin core.


Custom derivatives are available, please contact us at tech@jenkemusa.com for more information.
