Relating to, containing, or derived from acetone; having the properties or characteristics of acetone.
From acetone plus the suffix -ic (relating to), creating an adjective to describe things connected to or resembling acetone.
The -ic suffix is chemistry's way of saying 'made of' or 'like'—so acetonic just means 'acetone-like' or 'acetone-related,' which is why chemists can quickly describe the nature of a compound or reaction without lengthy explanations.
