Methyl isobutyl ketone (CH3COCH2CH(CH3)2) is a branched acyclic ketone widely used as a solvent in paints, inks, and extraction processes. HTS 2914.19.00.00 covers this as an 'other' acyclic ketone lacking additional oxygen functions, aligning with Chapter 29 for pure organic compounds. Its volatility suits industrial applications without formulation exclusions.
