I received Product D8418, Dimethyl sulfoxide, as a frozen solid. But isn't it supposed to be in the liquid state?
1 answer-
DMSO super cools easily and remelts slowly at room temperature. The product may arrive as a solid instead of a liquid. The solidified product can be reliquified by warming to room temperature without detriment to the product.
