Molecule of the Week

I’m a familiar solvent, but I have other uses. 

About Molecule of the Week

MOTW has been a popular feature on this site since 2001. Many molecules are suggested by our website visitors. Every structure is reviewed by a scientist and displayed in 3-D and flat images with a brief description.

Each week’s molecule also links to a sample record from the CAS REGISTRY, which is searched using SciFinder®. Each record displays the registry number, index name and synonyms, bibliographic information, and more.
