Questions

  1. Hi, I hope this message finds you well. We would like to order the Levodopa (1361009 USP), could you please let me know how should we dissolve the reagent and how to store the solution? How long can we store the solution for cell culture use? Thank you!

    1 answer
    1. This product is slightly soluble in water and acidic solutions, and practically insoluble in ethanol. It is unstable in aqueous alkaline solutions. Solutions should be freshly prepared, as the product is rapidly oxidized by air and may darken when exposed to air and light.
