Nsi-189 Phosphate

NSI-189 Phosphate is a novel, synthetically produced neurogenic small molecule compound belonging to the benzylpiperazine-aminopyridine derivative family. Originally developed by Neuralstem, it is currently primarily used as a high-purity raw material for research, pharmaceutical intermediates, and basic development in related fields. In appearance, NSI-189 Phosphate is a white to off-white crystalline powder with no obvious odor. Its CAS number is 1270138-41-4, its molecular formula is C₂₂H₃₃N₄O₅P, and its molecular weight is 464.49. It exhibits stable physicochemical properties, is readily soluble in DMSO and methanol, and has moderate solubility in water. Compared to its non-phosphate form, its water solubility and stability are significantly improved. Its melting point is approximately 158–162℃ (decomposition state). It remains stable under sealed conditions at room temperature; for long-term storage, it is recommended to store it in a sealed environment at -20℃. As a high-purity pharmaceutical-grade raw material, the active ingredient in this product is a single entity, NSI-189 Phosphate, with a purity of over 99.0%, and high-end customized specifications can reach 99.8%–99.95%.
