|Reconstitution||Before reconstitution, we recommend a brief spin to drive down any material dislodged from the bottom of the tube. The compound is soluble in DMSO.|
|Stability||The powder is stable for at least 2 year if stored at -20 °C. The dissolved compound is stable for at least 1 month at 4 °C, but should be stored in aliquots at -20 °C for longer term. Protect from light.|
|Purity||Greater than 98% as determined by LC/MS analysis. LC/MS and/or NMR data available upon request.|
