What is DMSO classified as?
Classification. This chemical is considered hazardous by the 2012 OSHA Hazard Communication Standard (29 CFR 1910.1200) Label Elements. Signal Word.
What is DMSO used for in chemistry?
DMSO is frequently used as a solvent for chemical reactions involving salts, most notably Finkelstein reactions and other nucleophilic substitutions. It is also extensively used as an extractant in biochemistry and cell biology.
Is DMSO reactive?
DMSO Reactivity DMSO reacts very rapidly and vigorously with a number of materials, particularly with those that also react rapidly with water. The reactions are highly exothermic, with rapid steam or gas evolution.
Is DMSO toxic to humans?
This relatively high dose changed the view on DMSO toxicity and the FDA classified DMSO in the same class as ethanol, namely class 3 solvent, which is the safest category with low toxic potential at levels normally accepted in pharmaceuticals8. This made the wide use of DMSO possible.
Why is DMSO a good solvent?
They can dissolve a wide range of solutes and are miscible with many other solvents; this is true not only for polar compounds but also for some of low polarity, e.g., naphthalene and toluene. Being aprotic, DMSO and DMSO2 can tolerate relatively strong bases.
Is DMSO oxidizing?
Dimethyl sulfoxide acts as a mild room-temperature oxidant of luminescent porous silicon. The oxidation reaction is accompanied by a loss in photoluminescence intensity from the silicon nanocrystallites, indicating that the oxide formed under these conditions is electronically defective.
What reaction uses DMSO?
The Swern oxidation, named after Daniel Swern, is a chemical reaction whereby a primary or secondary alcohol is oxidized to an aldehyde or ketone using oxalyl chloride, dimethyl sulfoxide (DMSO) and an organic base, such as triethylamine.
Is DMSO legal for human use?
To date, the Food and Drug Administration (FDA) has officially approved the use of DMSO in humans for only one purpose: to treat interstitial cystitis. This is a chronic condition that causes inflammation in your bladder. To treat it, your doctor may flush DMSO into your bladder using a catheter over several of weeks.
