Tandospirone Citrate
China [CN] Tandospirone Citrate, also known as SM 3997 and Methanospirone, has CAS No. 112457-95-1, molecular formula C21H29N5O2·C6H8O7 and molecular weight of 575.615. It is a white to off-white solid pharmaceutical raw material with a melting point of 169.5–170°C and water solubility of 10.4 mg/mL (18.07 mM). For maximum stability, it must be stored under inert atmosphere at -20°C freezer condition, with its unique InChIKey provided for compound identification. As a selective anxiolytic small-molecule API targeting central nervous system receptors, we supply high-purity reagent-grade Tandospirone Citrate, alongside analytical reference standards, related impurities and deuterated derivative Tandospirone-D8 citrate. Complete technical documents including synthetic routes, MSDS, pharmacological activity data and chiral structural information are available to support laboratory testing, anxiety disorder drug research and preclinical pharmaceutical development programs.
