PEG Raw Materials

JenKem Technology’s high quality linear and multi-arm PEG raw materials (polyethylene glycol, PEG hydroxyl or PEG alcohol) are suitable for activation into PEG derivatives.

JenKem Technology’s methoxy PEG raw materials are high quality PEGs with very low polydispersity and low to no diol content. JenKem Technology controls its in-house direct polymerization processes such that high purity (>99%) methoxy polyethylene glycol raw materials can now be produced without the need for further purification. The benefit of these improvements will be passed along to our customers who need GMP grade methoxy PEG (mPEG) derivatives. This improved JenKem Technology capability ensures optimum control of batch to batch reproducibility and consistency of specifications to best meet the demanding requirements for conjugation to your protein, peptide, oligonucleotide, and/or small molecule.

JenKem Technology also provides PEG GPC Calibration Standard kits. JenKem Technology’s PEG GPC standards have narrower polydispersity and more accurate molecular weights compared to other PEG standards on the market.

Founded in 2001 by experts in PEG synthesis and PEGylation, JenKem Technology specializes exclusively in the development and manufacturing of high quality polyethylene glycol (PEG) products and derivatives, and related custom synthesis and PEGylation services. JenKem Technology is ISO 9001 and ISO 13485 certified, and adheres to ICH Q7A guidelines for GMP manufacture. The production of JenKem® PEGs is back-integrated to in-house polymerization from ethylene oxide, enabling facile traceability for regulated customers. JenKem Technology caters to the PEGylation needs of the pharmaceutical, biotechnology, medical device and diagnostics, and emerging chemical specialty markets, from laboratory scale through large commercial scale.
