Mal-PEG3-acid is a high-performance, high-purity product widely used in the fields of biotechnology and chemistry. It has a unique structure with PEG (polyethylene glycol) as the main chain, one end connected to a Mal (maleimide) group, and the other end being a carboxyl group (-COOH). This structure gives it good water solubility and reactivity. The production process undergoes strict quality control to ensure high purity and stability. Mal-PEG3-acid is commonly used in areas such as biomolecular modification, drug development, and polymer synthesis. Its professionalism and academic characteristics make it an important tool in biochemical research. Its precise structural design, rigorous production process, and broad application scenarios make Mal-PEG3-acid a reliable assistant for researchers.
