Storage and Handling

The majority of the compounds in dry form can be transported and stored long-term under ambient temperatures unless stated otherwise by TimTec at the time of quotation/order. Keeping products in slightly cooler than room temperature, dark space is preferred. Once compounds are dissolved in DMSO, acceptable storage temperature would be -20C and -80C, for long-term storage. Solvent use, solvent/s composition as well as storage conditions are largely determined by assays and the specifics of product/s use. Compounds stability in DMSO might be affected by thaw-freeze cycles. TimTec is not responsible for any quality claims related to customers’ in-house storage decisions.  TimTec would advise consulting with reference materials on product handling and storage related to customers’ particular application.
