The ampule cannot be resealed after opening. The contents may be transferred to a tightly closed amber glass vial. This product is light- and oxidation-sensitive and should be handled and stored under an inert gas (e.g., nitrogen or argon) at -20 °C. Room-temperature storage is not recommended for either the solid form or prepared stock solutions. Stock and working solutions can be prepared at room temperature, but should be aliquoted and stored frozen under inert atmosphere to maintain stability. The solubility and solution stability of this material hasve not been determined. Other sources indicate that stock solutions may be prepared in chloroform at ~50 mg/mL or DMSO at 100 mg/mL. Other solvents such as ethanol and methanol are also cited in various literature. Stock solutions may be stored in working aliquots at -20 °C under argon or nitrogen for up to 6 months. Avoid repeated freeze/thaw cycles.
