This compound is supplied as a lyophilized powder under sterile vacuum sealing. Reconstitute using sterile bacteriostatic water. For optimal dissolution, gently swirl the vial; do not shake vigorously.

Three-step educational workflow for preparing and refrigerating a 20mg research vial
  1. 1. Prepare. Confirm the vial identity, diluent, lot details, and a clean workspace.
  2. 2. Follow protocol. Use only the validated procedure for your specific research compound.
  3. 3. Label and store. Record the date and handling details, then follow the label and SOP for storage.
