Description

Pentanoic acid (CAS 109-52-4 ), also known as valeric acid, is a five-carbon saturated carboxylic acid used across food, fragrance, and pharmaceutical manufacturing. It functions primarily as a flavoring agent and pH regulator. This versatile compound serves as a critical chemical intermediate in the synthesis of esters and active compounds. In food and beverage production, it contributes characteristic dairy and fruity top notes to flavors. The substance is listed under FEMA 3101 for use in approved applications. Ester derivatives, particularly pentyl acetate and related compounds, are produced using this acid as a key synthesis intermediate. Pharmaceutical manufacturers use it as a precursor in the synthesis of valproic acid and other active pharmaceutical ingredients. In industrial settings, it functions as a catalyst precursor and pH-buffering agent. It is particularly useful in organic synthesis processes where controlled acidity is required. The product is supplied as a colorless liquid in bulk quantities, intermediate IBCs, and smaller drum formats. These packaging options are suited to laboratory or pilot-scale procurement. Food-grade material conforming to FCC specifications is available for flavor and food additive applications. Technical-grade supply is standard for industrial synthesis and catalyst preparation end uses.
