Uses
Methyl chloroformate is used in organic synthesis for the introduction of the methoxycarbonyl functionality to a suitable nucleophile (i.e. carbomethoxylation).[2]
Safety
Methyl chloroformate, if heated, releases phosgene. It produces hydrogen chloride upon contact with water. It will cause skin damage if in contact with skin.
gollark: Not sure it's their fault. Consciousness is just tricky.
gollark: And consciousness is too poorly defined to mean anything much anyway.
gollark: Wrong. It isn't the issue.
gollark: People assume quantum computers are magic do-anything boxes, that regular computers "can't be random", that AI is "incapable of creativity" or might randomly become "conscious"/"sentient"/humanlike and rebel, etc.
gollark: Perhaps people just don't actually care much about accurate beliefs in subjects they don't personally use much, and vaguely assume that whatever they know about those things is right enough to discuss politics and whatever.
