A clear liquid with colorless to yellowish colour with a sweet pungent taste and odor resembling the odor of oranges. Melting point 20.5°C (68.9°F); freezes under cool conditions. Slightly soluble in water and denser than water.  Hence sinks in water.  Vapor heavier than air.  A mild irritant to skin and eyes.  Vapors can be narcotic in high concentrations.  Used as a flavoring, solvent, and polymerization catalyst.
Synonyms Methyl phenyl ketone, 1-Phenylethanone, Phenylethanone, ACP
