Description

Butyl Levulinate is a versatile ester derived from levulinic acid, serving as a valuable intermediate and solvent in advanced chemical synthesis. Its unique properties make it a critical component for formulators seeking high-performance, bio-based solutions with excellent solvency and reactivity. This product is essential for manufacturers in the fragrance, polymer, and specialty chemical industries, where it functions as a green solvent, plasticizer, and flavor/fragrance precursor. We supply high-purity Butyl Levulinate CAS NO 2052-15-5 to meet the stringent demands of global industrial and research applications.

Application

• Fragrance and Flavor Ingredient: Used as a precursor and solvent in the synthesis of complex aroma chemicals and flavoring agents.
• Green Solvent: Acts as an effective, renewable solvent in coatings, inks, and cleaning formulations, replacing traditional volatile organic compounds (VOCs).
• Polymer and Plasticizer Intermediate: Serves as a building block for producing specialty polymers, resins, and bio-based plasticizers.
• Pharmaceutical Synthesis: Utilized as an intermediate in the manufacture of active pharmaceutical ingredients (APIs) and other fine chemicals.
• Fuel and Fuel Additive: Investigated for use as a bio-derived fuel component or an additive to improve fuel properties.
• Chemical Research & Development: Employed as a reagent and solvent in organic synthesis and material science research.

Quality Control

Our Butyl Levulinate is manufactured under strict quality management systems to ensure batch-to-batch consistency and high purity. Each lot is tested against rigorous internal specifications, which typically include assay, identity confirmation, and impurity profiling. A Certificate of Analysis (COA) detailing all test results is provided with every shipment. We adhere to ISO guidelines and can support compliance with REACH and other relevant global regulatory frameworks.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, well-ventilated area away from heat sources and incompatible materials such as strong acids and oxidizing agents. Recommended storage temperature is between 15°C and 25°C (59°F and 77°F). Keep container tightly sealed when not in use to minimize moisture absorption and evaporation.
