JenKem Technology manufactures high quality polyethylene glycol (PEG) raw materials with high purity and low polydispersity. In-house PEG production is back-integrated to the ethylene oxide starting material. JenKem Technology ‘s hydroxyl PEG raw materials (PEG alcohols) are suitable for further derivatization into PEG derivatives. JenKem® PEG raw materials are sold in bulk without purification after polymerization. Please contact us at firstname.lastname@example.org for inquiries on the availability of purified or research grade PEG raw materials.
JenKem Technology provides high quality linear polyethylene glycol hydroxyl raw materials with high purity, low polydispersity, and low to no diol content. Linear monofunctional methoxy PEG raw materials are end-capped with a methoxy group or benzyl group. Linear Methoxy PEG Hydroxyl raw materials are provided as bulk orders of 1kg or more, with the molecular weights of 5kDa, 10kDa, 20kDa, 30kDa, and 40kDa. JenKem Technology also provides a GPC Calibration Standard kit for linear methoxy PEGs (STDMPEG) containing 200mg each of linear PEGs with MW of 2kDa, 5kDa, 10kDa, 20kDa and 40kDa.
JenKem Technology now provides proprietary 8ARM(TP)-PEG hydroxyl raw materials with tripentaerythritol core. 8ARM(TP)-PEGs with tripentaerythritol core have a higher purity as evidenced by MALDI compared with the generic 8ARM-PEGs with a hexaglycerin core.
The molecular weight of JenKem Technology’s multi-arm PEG hydroxyl raw materials is the sum of the molecular weights of all of the arms. Each arm may have different lengths. JenKem Technology’s PEG raw materials with molecular weights not listed in our online catalog may be available by custom synthesis. Please inquire at email@example.com about pricing and availability.
