Product Overview
Succinimide (CAS 123-56-8), also known as 2,5-Pyrrolidinedione or Butanimide, is a cyclic imide compound with a five-membered ring structure. It appears as a white to off-white crystalline powder or needle-like crystals, nearly odorless with a slightly sweet taste. Featuring high purity, good water solubility and stable chemical properties, it is widely used in organic synthesis, pharmaceutical manufacturing, chemical analysis and electroplating industries. Produced via strict purification processes, the product ensures low impurities and consistent batch quality. For legitimate industrial production, formulation and scientific research only.
