Functionalized PEGs
With inventory located in the US to avoid customs delays, high-purity functionalized PEGs are now available from Frontier Specialty Chemicals through a strategic partnership with AMT (Advanced Molecular Technologies). This collaboration makes AMT’s state-of-the-art PEG technologies more accessible to researchers globally, offering controlled molecular weights, precise functional end groups, and excellent solubility.
Functionalized PEGs support a wide range of applications across life sciences and materials science, supporting applications that require solubility control, biocompatibility, and surface modification.
-
PEGS for Life sciences: drug delivery, bioconjugation, diagnostics, fluorescent PEGs, biointerfaces, PEGylation
-
PEGs for Materials science: polymers, coatings, surface modification, advanced formulations
Our high-purity PEGS are available in catalog and bulk quantities, as well as GMP quality materials to support reliable results from early research through scale-up.
We also offer Custom Synthesis of unique PEG analogs!
