Storage

Preserve in a tightly closed container, protected from light. Due to its thiol functionality and propensity to be easily oxidized, this material should be stored under an inert atmosphere (argon or nitrogen) at a controlled room temperature (15-25°C). The container must be kept in a cool, dry, and well-ventilated place, away from oxidizing agents.
