PEG (Amine)2, HCl Salt


PEG products with additional MW may be made to order, please contact us for details



PEG (Amine)2, HCl Salt product with superior quality specification of ≥95% Substitution.

PEG (Amine)2, HCl Salt from JenKem Technology (diamine PEG) is a homobifunctional PEG employed for pegylation via stable linkages, such as amide, urethane, urea, or secondary amine. The HCl salt form provides stability for the solid form of Amine PEG Amine. Homobifunctional PEG derivatives from JenKem Technology have numerous applications as crosslinkers for PEGylation of proteins and peptides, nanoparticle and surface modifications. Conjugation with homobifunctional PEGs provides an increased drug load compared to pegylation using linear PEGs. JenKem Technology offers PEG (Amine)2, HCl Salt with MW 2,000 Da (NH2HCl-PEG2000-NH2HCl), MW 3,500 Da (NH2HCl-PEG3500-NH2HCl), MW 5,000 Da (NH2HCl-PEG5000-NH2HCl), and MW 7,500 Da (NH2HCl-PEG7500-NH2HCl), in 1g and 5g packing sizes.

Different MW of  PEG diAmine may be available by custom synthesis, please email us at for details on custom PEGs. JenKem Technology provides repackaging services for an additional fee, please contact us if you require a different package size than our catalog selection. Bulk PEGs and GMP PEGs are also available upon request. Please contact us for special bulk pricing.

Note: Starting July 2016, PEG (Amine)2, HCl Salt is the new name of the product Amine PEG Amine HCl salt (MW 2000 (NH2-PEG2000-NH2), MW 3500 (NH2-PEG3500-NH2), MW 5000 (NH2-PEG5000-NH2) and MW 7500 (NH2-PEG7500-NH2)).
