Product Name:Amine-PEG-Amine
English Name:Amine-PEG-Amine
CAS No.:479200-82-3
Aliases:NH2-PEG-NH2, Diamino PEG, Bis-amine PEG
Molecular Formula:H2NCH2CH2(CH2CH2O)nCH2CH2NH2
Physical Properties:White to off-white solid or viscous liquid depending on molecular weight. Soluble in dichloromethane, chloroform, acetone, DMF, DMSO, toluene, methanol, and ethanol (10 mg/mL in DMSO). Slightly soluble in water; insoluble in paraffin oil. Store refrigerated and avoid repeated freeze-thaw cycles.
Uses:NH2-PEG-NH2 is a bifunctional polyethylene glycol derivative containing two primary amine groups. The amine groups readily react with NHS esters, carboxylic acids, aldehydes, and other amine-reactive functional groups in aqueous buffers or organic solvents. It serves as a PEGylation reagent for modifying proteins, peptides, particles, and other biomaterials, and is widely used in scientific research and pharmaceutical chemistry.
Technical Specifications:
Molecular weight: 2000, 3400, 5000; custom molecular weight available
High purity with narrow molecular weight distribution
Storage: keep dry at 2-8 °C under inert gas; retest after 24 months
Packaging: 1 g (customizable)
Contains two primary amine groups reactive with COOH and NHS
