Abstract

The present disclosure provides polymorphic forms of sodium benzoate with a X-ray diffraction pattern comprising characteristic peaks at a reflection angle 2θ of approximately 5.9, 30.2, and 31.2 degrees; or a X-ray diffraction pattern comprising characteristic peaks at a reflection angle 2θ of approximately 3.7, 5.9, and 26.6 degrees. Also provided herein are methods of preparing the polymorphic forms of sodium benzoate and uses thereof in treating and/or reducing the risk for a neuropsychiatric disorder (e.g., schizophrenia, psychotic disorders, depressive disorders, or Alzheimer'"'"'s disease).
