Infobox disclaimer and references

Acetone cyanohydrin is an organic compound used in the production of methyl methacrylate, the monomer of the transparent plastic polymethyl methacrylate (PMMA), also known as acrylic.

Acetone cyanohydrin is classified as an extremely hazardous substance in the US Emergency Planning and Community Right-to-Know Act.

The principal hazards of acetone cyanohydrin are due to its ready decomposition into acetone and the highly toxic hydrogen cyanide: it rapidly decomposes on contact with water.
