Tiglic acid is a naturally occurring, unsaturated carboxylic acid (C₅H₈O₂) with a pungent, spicy odor, existing as the trans-isomer to angelic acid, found in croton oil and some plants, used in perfumes, flavorings, and as a chemical intermediate for pharmaceuticals, but is a skin/eye irritant requiring careful handling. It's a crystalline solid (or liquid) that's reactive due to its double bond, serving as a building block in organic synthesis.
