Clear, colorless to amber liquid.
Experimentally as mutagen, teratogen, brain carcinogen.
Methyl methanesulfonate is a DNA adduct that adds methyl groups to Dan at 7-guanine, 3-guanine and 3-adenine.
ChEBI: A methanesulfonate ester resulting from the formal condensation of methanesulfonic acid with methanol.
Colorless to amber liquid.
Methyl methanesulfonate is incompatible with strong oxidizing agents, strong acids and strong bases.
Methyl methanesulfonate is combustible.
Confirmed carcinogen
with carcinogenic and neoplastigenic data.
Poison by ingestion, intraperitoneal,
intravenous, and subcutaneous routes.
Human mutation data reported.
Experimental teratogenic and reproductive
effects. When heated to decomposition it
emits toxic fumes of SOx.
Research chemical and cancer drug.
No longer produced commercially in the United States.
Methyl methanesulfonate is reascarcinogen based on sufficient evi
onably anticipated to be a human dence of carcinogenicity from studies in experimental animals.

Purify the ester by careful fractionation and collecting the middle fraction. Suspected CARCINOGEN. Note that MeSO3H has b 167-167.5o/10mm and methanesulfonic anhydride has b 138o/10mm)—both are possible impurities. [Beilstein 4 IV 11.]
Incompatible with oxidizers (chlorates,
nitrates, peroxides, permanganates, perchlorates, chlorine,
bromine, fluorine, etc.); contact may cause fires or explosions. Keep away from alkaline materials, strong bases,
strong acids, oxoacids, epoxides. Esters are generally
incompatible with nitrates. Moisture may cause hydrolysis
or other forms of decomposition
It is inappropriate and possibly dangerous to the environment to dispose of lab chemicals or expired or waste drugs and pharmaceuticals by
flushing them down the toilet or discarding them to the
trash. Household quantities of expired or waste pharmaceuticals may be mixed with wet cat litter or coffee
grounds, double-bagged in plastic, discard in trash.
Larger quantities shall carefully take into consideration
applicable DEA, EPA, and FDA regulations. If possible
return the pharmaceutical to the manufacturer for proper
disposal being careful to properly label and securely
package the material. Alternatively, the waste pharmaceutical shall be labeled, securely packaged, and transported
by a state licensed medical waste contractor to dispose by
burial in a licensed hazardous or toxic waste landfill or
incinerator.
