Polysuccinimide CAS#5608-40-6
Polysuccinimide, identified by the CAS number 5608-40-6, typically appears as a white or off-white powdery solid. It does not dissolve in conventional organic solvents like water, ethanol, and acetone, though it can achieve partial dissolution or undergo swelling when in contact with certain strongly polar solvents—dimethyl sulfoxide (DMSO) and N-methylpyrrolidone (NMP) being examples of such solvents.

Product Application of Polysuccinimide CAS#5608-40-6
Polysuccinimide (CAS#5608-40-6) is a degradable polymeric material with extensive application prospects. Polyaspartic acid, the product of its hydrolysis, serves as a phosphorus-free water treatment agent—capable of preventing scale formation and adsorbing heavy metals in wastewater—while also functioning as a fertilizer synergist to boost plant growth. Within the medical field, it can be modified into drug sustained-release carriers or applied in biocompatible materials. Additionally, it can be blended with other polymers to produce degradable plastics, and finds use as a drilling fluid additive, a cosmetic moisturizing agent, and in other similar applications.
