t-Boc Amine PEG Acetic Acid


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


High quality t-Boc Amine PEG Acetic Acid with standard quality specification of ≥95% Substitution.

Heterobifunctional t-Boc Amine PEG Acetic Acid products with protected amine from JenKem Technology are generally employed as crosslinking agents or as spacers between two different chemical entities. The PEG moiety in the heterobifunctional  tBoc Amine PEG Carboxyl PEG derivatives provides water solubility, biocompatibility, and flexibility. Applications are especially geared towards the development of antibody drug conjugates (ADC’s).

Heterobifunctional PEGylation reagents with molecular weights, branching, and functional groups not listed in our online catalog may be available by custom synthesis. Please inquire at tech@jenkemusa.com about pricing and availability of custom PEGs.

Bulk PEGs and GMP grade PEGs are made-to-order. Please contact us for bulk pricing.

Note: Starting July 2016, t-Boc Amine PEG Acetic Acid is the new name of the product t-Boc Amine PEG Carboxyl (MW 2000 (TBOC-PEG2000-COOH), MW 3500 (TBOC-PEG3500-COOH), MW 5000 (TBOC-PEG5000-COOH) and MW 7500 (TBOC-PEG7500-COOH)). JenKem Technology has revised the name of the product to better reflect the chemical structure, as many other PEG derivatives with a COOH group are offered in the 2016 JenKem USA catalog.

Starting September 2017, the item code for these products has been changed to TBOCNH-PEG5000-CM. This is only a name change implemented to better reflect the chemical structure of TBOC-PEG-COOH.

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.
