Questions

  1. Hello! I need to know whether I can prepare the working solution of the Ibudilast powder by diluting it in DMSO and freezing for storage at -20C. Will the compound be not degraded or damaged after freezing?

    1 answer
    1. This product is soluble in DMSO at 28 mg/mL. The recommended storage temperature is 2-8°C
      Please see the product data sheet for more information:
      https://www.sigmaaldrich.com/deepweb/assets/sigmaaldrich/product/documents/268/374/i0157dat.pdf

      However, solutions in DMSO or ethanol may be stored at -20°C for up to 3 months. The end-user will need to be cautious about keeping the product at -20°C for long-term storage and determine the stability at such temperatures empirically as this is not tested internally.
