PEG Raw Materials
The following PEG raw materials are intended for use to make PEG derivatives. PEG raw materials are sold without any purification after polymerization. If you need PEG raw materials for dedicated research work, please contact us for research grade PEG raw materials.
Linear Methoxy PEG Raw Materials
PEG raw materials are provided as bulk order to end users in the molecular weight of 5000Da, 10000Da, 20000Da, 30000Da, and 40000Da. The methoxy PEG raw materials are one end-capped with a methoxy group and are monofunctional.
The structure of methoxy PEG is as the following:
ITEM CODE | ITEM NUMBER | ITEM DESCRIPTION | PRICE (USD/KG) |
P1005 | M-PEG-5000 | Methoxy Polyethylene Glycol, MW 5000 | $3500 |
P1006 | M-PEG-10K | Methoxy Polyethylene Glycol, MW 10000 | $3500 |
P1009 | M-PEG-20K | Methoxy Polyethylene Glycol, MW 20000 | $4500 |
P1010 | M-PEG-30K | Methoxy Polyethylene Glycol, MW 30000 | $5500 |
P1012 | M-PEG-40K | Methoxy Polyethylene Glycol, MW 40000 | $6000 |
Multi-arm PEG Raw Materials
Multi-arm PEG raw materials are provided 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.
4ARM-PEG-OH is prepared by ethoxylation of pentaerythritol.
8ARM-PEG-OH is prepared by ethoxylation of hexaglycerine or tripentaerythritol core.
JenKem now provides new 8ARM-PEG with tripentaerythritol core. The 8ARM-PEG-OH 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 your custom synthesis need.
