• Background Description

• Pomalidomide is an immunomodulatory agent for treating multiple myeloma. In its synthesis, incomplete esterification reactions or raw material residues easily generate impurities such as methyl 5-amino-4-(1,3-dioxoisoindolin-2-yl)-5-oxopentanoate. Such impurities may affect drug safety and effectiveness, making research on them a key part of pomalidomide quality control.

• Research Status

• Current research focuses on:
• 
  

• Detection Method Optimization: Establishing trace detection methods (detection limits reach ppb level) using ultra-high-performance liquid chromatography-tandem mass spectrometry (UPLC-MS/MS);

• Synthesis Process Improvement: Reducing impurity generation by optimizing reaction temperature and catalyst types;

• Toxicological Evaluation: Studying the potential toxicity of this impurity through in vitro cell experiments and animal models;

• Crystal Form Research: Analyzing the impact of impurity crystal forms on drug formulation stability to improve the quality control system.
