CAS No.: 83373-60-8; D609 potassium salt. PROPERTIES: D609 potassium salt is a white crystalline powder with a molecular weight of approximately 392.5 g/mol. Its chemical formula is C20H20KNO5S. The compound is freely soluble in water and ethanol but sparingly soluble in organic solvents. It should be stored at room temperature in airtight containers. Stability is maintained for at least two years under proper storage conditions. Safety precautions include avoiding ingestion and using standard laboratory PPE during handling. The substance is irritating to eyes, respiratory system, and skin. APPLICATIONS: D609 potassium salt is a potent and selective inhibitor of phosphatidylcholine-specific phospholipase C (PC-PLC). It is widely used in biochemistry research to study the role of PC-PLC in cellular signaling pathways. In cell culture models, D609 demonstrates efficacy in blocking proliferation of various cancer cell lines by disrupting lipid signaling networks. The compound has also been employed in studying platelet activation and aggregation mechanisms. Additionally, D609 potassium salt serves as a research tool for investigating the pathophysiology of inflammatory disorders. These applications are supported by scientific literature from biochemical research publications and pharmaceutical development documents.
