Collection: PEGylation Reagents (for DDS)

PEGylation Reagents (for DDS) — a collection of short-chain ethylene glycol-based reagents such as tri- and tetraethylene glycol with bromo, azido, or methyl ether functional groups at the chain end. These reagents act as hydrophilic linkers for PEGylation modification of molecules and drug delivery systems (DDS).

PEGylation Reagents are used in the synthesis of drug-polymer conjugates and nanoparticle surface modification to improve solubility and circulation of target molecules through substitution reactions or click chemistry with azide groups. Pharmaceutical and bioorganic chemistry researchers use these short-chain bromo and azido derivatives as linkers between target ligands and PEG polymer carriers.

Example products in this collection: TCI T2634 110429-45-3 Triethylene Glycol 2-Bromoethyl Methyl Ether, TCI D2904 2050595-03-2 Dodecaethylene Glycol Monomethyl Ether, TCI T1372 23783-42-8 Tetraethylene Glycol Monomethyl Ether, TCI D3831 72593-77-2 Diethylene Glycol 2-Bromoethyl Methyl Ether, TCI B4736 54149-17-6 1-Bromo-2-(2-methoxyethoxy)ethane (stabilized with Na2CO3), TCI H0808 23601-40-3 Hexaethylene Glycol Monomethyl Ether, TCI A2728 606130-90-9 13-Azido-2,5,8,11-tetraoxatridecane, TCI H1046 4437-01-8 Heptaethylene Glycol Monomethyl Ether.

Adjust the ethylene glycol chain length and terminal group type (bromo, azido, or methyl ether) to the planned conjugation strategy, and pay attention to reagent purity so that PEGylation results are uniform. All products are genuine Tokyo Chemical Industry (TCI) Japan products, with purity, packaging, and storage conditions listed on each item's page.
