Pentadecanoic acid(CAT: R039988), also known as C15:0 or pentadecylic acid (C₁₅H₃₀O₂), is a saturated odd-chain fatty acid found in trace amounts in dairy fat, certain fish, and some plants. It appears as a white crystalline solid or oily substance, insoluble in water but soluble in organic solvents. In nutrition research, pentadecanoic acid is studied as a potential biomarker of dairy fat intake and has been associated with beneficial effects on metabolic health, including improved lipid profiles and reduced inflammation. Industrially, it is used in the synthesis of lubricants, surfactants, and specialty chemicals, as well as in cosmetic formulations for emollient properties.
