Hydroxyl PEG12 Acetic Acid


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


Monodisperse Hydroxyl PEG12 Acetic Acid reagent with superior quality specification of ≥ 95% Purity.

Monodisperse Hydroxyl PEG12 Acetic Acid (Hydroxyl PEG12 Carboxyl, HO-PEG12-CM) from JenKem Technology is generally employed as crosslinking agent, or spacer between two different chemical entities. The PEG moiety in the single molecule discrete heterofunctional PEG derivatives provides water solubility, biocompatibility, and flexibility.

Monodisperse heterobifunctional PEGylation reagents with molecular weights 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.

Read about select applications of JenKem® PEGs in the medical device, drug development, and diagnostics areas, including drug delivery, wound healing, cell culture models, and tissue regeneration.

Note: Starting July 2016, Monodisperse Hydroxyl PEG Acetic Acid is the new name of the product Monodisperse Hydroxyl PEG Carboxyl (MW 428.5 (HO-PEG8-CM), MW 604.8 (HO-PEG12-CM)). 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.

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 polymer 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.
