Polysuccinimide CAS#5608-40-6

Excellent Structural Stability: Polysuccinimide exists as a durable white to off-white powdered material, guaranteeing consistent and stable performance across a wide range of usage scenarios.
Low Compatibility with Conventional Solvents: Being insoluble in water, ethanol and acetone, it is well suited for targeted preparation systems that demand strict control over dissolution behavior.
Controlled Solubility in Strong Polar Media: It is able to undergo partial dissolution or swelling in highly polar solvents such as DMSO and NMP, providing adjustable applicability for professional industrial production demands.
Strong Resistance to Harsh Chemical Environments: Given its tolerance to ordinary organic solvents, it serves as a preferred option for working conditions that require outstanding chemical durability.

Product Details
Polysuccinimide (CAS#5608-40-6) normally presents as a white or off-white crystalline powder. It shows no solubility in routine solvents such as water, ethanol and acetone, yet is capable of partial dissolution or swelling in highly polar solvents like dimethyl sulfoxide (DMSO) and N-methylpyrrolidone (NMP).
