Product Description of DNP-PEG2-acid
DNP-PEG2-acid (CAS 1353011-89-8) is a functionalized polyethylene glycol derivative with the molecular formula C₁₃H₁₇N₃O₈ and a molecular weight of 343.3. Its structure consists of three components: 2,4-dinitroaniline (DNP) provides strong optical absorption properties, diethylene glycol (PEG2) enhances water solubility and biocompatibility, and the terminal carboxyl group (-COOH) serves as an active conjugation site. The production process involves introducing the DNP group via nitration, followed by covalent coupling with a PEG2-carboxylic acid intermediate, resulting in a high-purity product (≥95%) after purification. This compound is widely used in immunoassays (e.g., ELISA signal amplification), drug delivery system construction (carboxyl-mediated coupling of targeting molecules), nanomaterial surface modification (reducing nonspecific adsorption), and molecular probe development, making it a key tool molecule in biomedical and materials science fields.
