Decay/Reactivity of DMSO and MSM

[Mk]

How long can one store dimethyl sulfoxide (DMSO) or methylsulfonylmethane (MSM)?

I don't have any experience with MSM, but have never had DMSO go bad. DMSO is one of those things we use a little bit every few years, and then sits on a shelf in between, and still seems just fine. I've known a few people to store it in the fridge if stored a long time, rather than at room temp (so it will freeze), but I haven't noticed any difference between the two storage methods other than the nuisance of having to wait for it to thaw when taken out of the fridge.

I can provide you with a response regarding the decay and reactivity of DMSO and MSM. Dimethyl sulfoxide (DMSO) and methylsulfonylmethane (MSM) are both organic compounds that are commonly used in various industries, including pharmaceuticals and cosmetics.

Firstly, DMSO and MSM are both highly stable compounds and do not readily undergo decay. However, they can react with certain chemicals, such as strong acids or oxidizing agents, which can lead to their decomposition. Therefore, it is important to store DMSO and MSM in a cool, dry place and avoid exposure to extreme temperatures or incompatible substances.

The shelf life of DMSO and MSM can vary depending on the specific storage conditions and the purity of the compounds. Generally, DMSO has a longer shelf life compared to MSM, with an average of 2-3 years if stored properly. On the other hand, MSM can last for 1-2 years under ideal storage conditions.

It is important to note that the purity of DMSO and MSM can also affect their stability and shelf life. Impurities or contaminants in the compounds can accelerate their decay or reactivity, leading to a shorter shelf life.

In conclusion, DMSO and MSM are stable compounds with a relatively long shelf life if stored properly. It is recommended to follow the storage guidelines and regularly check the purity of these compounds to ensure their stability and effectiveness.
