NMU

I love Marquette, but let’s be honest - the winters are pretty depressing. I was feeling a little down today, being cooped up indoors since it was about -11 and a whiteout. I decided to look at some pictures that I had taken of past winters I’ve spent here, and was reminded that even with the isolation and the cold, there is a lot of beauty in these frigid months. There is something really beautiful about a day spent in a cozy coffee shop, or exploring familiar sites that have been completely transformed by ice. This winter, instead of looking at the things that I can’t do because of the cold and snow, I am going to try to recognize the unique experiences that come with UP winters.

Bucket chemistry: How NOT to perform a reaction.

In a nearly lab someone made a larger amount of N-Nitroso-N-methylurea (NMU) what is the direct precusor to diazomethane. The synthesis is quite easy, only some sodium nitrite should be added to an acidic N-methylurea solution at a low temperature to avoid the decomposition of the product. After everything is added, it should be filtered and washed with water to obtain pure product. Important note: NMU should be stored wet and should be never dried, since its pretty explosive in dry form. 

The problem with this is: “N-Nitroso-N-methylurea (NMU) is a highly reliable carcinogen, mutagen, and teratogen. NMU is an alkylating agent, and exhibits its toxicity by transferring its methyl group to nucleobases in nucleic acids, which can lead to AT:GC transition mutations.” So you can get cancer from this stuff quite easily. Extra info: in the bucket there is 600g of this compound.
