I. [Product Introduction]
Mal-NH-PEG-COOH (CAS 2112731-42-5) is a bifunctional organic intermediate. Through the specific binding of the maleimide group to the sulfhydryl group and the further coupling ability of the carboxyl group, it is widely used in the fields of bioconjugation and material modification. Its polyethylene glycol (PEG) segment provides excellent water solubility and anti-protein adsorption properties, making it an ideal choice for the synthesis of pharmaceutical intermediates and the design of catalyst carriers.

II. [Product Details]
【Appearance】 Depending on the molecular weight, it appears as a white/off-white solid or a viscous liquid.
【Stability】 Store refrigerated and avoid repeated freeze-thaw cycles.
【Solvent】 Conventional organic solvents such as chloroform, dichloromethane, and DMSO.
【Molecular Weight】 (PEG): 2000, 3400, 5000. Other molecular weights can be customized.
