JenKem PEG RnDJenKem Technology provides high purity monodisperse (discrete) PEG raw materials and monodisperse (discrete) PEG derivatives with an extensive variety of functional groups, from grams to kilograms batch size in both non-GMP and GMP grade. JenKem Technology’s monodisperse PEG products consist of linear chains of up to 108 –CH2-CH2-O– units (MW ~ 5000Da).

JenKem Technology’s monodisperse PEG products are produced via very reproducible chemical reactions and lack the polydispersity of traditional PEG polymers. Monodisperse PEGs retain polyethylene glycol’s good solubility in water, offering to PEGylated drugs the same PEG benefits of reduced aggregation and immunogenicity, and increased hydrodynamic volume.

JenKem Technology provides GMP grade discrete PEG derivatives and bulk orders via custom synthesis, offering the opportunity to match customers’ special quality requirements. JenKem Technology is capable of development and synthesis of a wide range of GMP monodisperse PEG derivatives starting at 200g up to 15 kg or greater batches, under ISO 9001 and ISO 13485 certified quality management system, following ICH Q7A guidelines.
