  • Applications

    5-Oxodecanoic acid (CAS 624-01-1) is a keto carboxylic acid featuring a carbonyl at position 5 and is mainly used as an intermediate in organic synthesis. In industrial applications, it serves as a building block for the preparation of esters and other derivatives, enabling use in fragrance and flavor chemistry; as a precursor for polymers and specialty plastics or for plasticizer/additive development; as a synthetic intermediate in pharmaceutical and agrochemical synthesis; and as a precursor for coatings and inks through derivatization to resinous intermediates.
