Description

Butyl levulinate (CAS 2052-15-5 ), also known by its FEMA 2207 designation, is a levulinic acid ester used commercially as a plasticizer, solvent, and flavoring agent. Derived from renewable feedstocks, it bridges bio-based chemistry with industrial performance across multiple end-use sectors. In plastics and polymer formulations, it functions as a plasticizer and softener. It improves flexibility and processability in PVC and biopolymer compounds. As a solvent and carrier, it supports coating, ink, and adhesive formulations where moderate evaporation rate and good solvency are required. Food and beverage manufacturers use it as a flavoring agent under FEMA 2207, where it contributes fruity, caramel-like notes to confectionery, baked goods, and beverages. Lubricant and metalworking formulators also incorporate it as a bio-based carrier fluid or diluent in specialty blends targeting sustainability requirements for modern industrial applications. Butyl levulinate is supplied as a clear liquid in standard drum and IBC quantities, with bulk tanker options available for larger procurement volumes across global supply chains. Food-grade material is available meeting FEMA specifications, while technical-grade product serves industrial solvent and plasticizer applications with high efficiency and reliability. Purity levels typically range from 98% upward, with certificate of analysis documentation standard across both grades to ensure compliance with rigorous internal quality control protocols.
