Descriptions:
pubchem: Butan-2-one is a dialkyl ketone that is a four-carbon ketone carrying a single keto- group at position C-2. It has a role as a polar aprotic solvent and a bacterial metabolite. It is a volatile organic compound, a dialkyl ketone, a butanone and a methyl ketone.
chebi: A dialkyl ketone that is a four-carbon ketone carrying a single keto- group at position <em>C</em>-2.
chembl: BUTANONE is a small molecule listed in the ChEMBL database but has not progressed to an approved clinical phase.
wikipedia: Butanone, also known as methyl ethyl ketone (MEK) or ethyl methyl ketone, is an organic compound with the formula CH3C(O)CH2CH3. This colorless liquid ketone has a sharp, sweet odor reminiscent of acetone. It is produced industrially on a large scale, but occurs in nature only in trace amounts. It is partially soluble in water, and is commonly used as an industrial solvent. It is an isomer of another solvent, tetrahydrofuran.
