Description

3-Methyl-2-Butanol is a versatile branched-chain alcohol with a distinctive odor, widely used as a key intermediate and solvent in industrial synthesis. Its value lies in its ability to act as a building block for flavors, fragrances, and specialty chemicals, offering a balance of reactivity and solubility. This product is essential for manufacturers in the flavor & fragrance, pharmaceutical, and agrochemical sectors seeking a reliable and high-purity chemical feedstock.

Application

• Flavor and Fragrance Ingredient: Serves as a precursor for esters used in creating fruity and floral aroma compounds.
• Pharmaceutical Intermediate: Utilized in the synthesis of active pharmaceutical ingredients (APIs) and other fine chemicals.
• Agrochemical Synthesis: Acts as a building block in the production of certain pesticides and herbicides.
• Solvent for Resins and Coatings: Employed as a solvent in formulations for specialty paints, lacquers, and resin systems.
• Chemical Research & Development: Used as a reagent in organic synthesis and laboratory-scale chemical processes.
• Plasticizer Production: Can be used in the manufacture of certain plasticizers and stabilizers.

Quality Control

Our 3-Methyl-2-Butanol is produced under a strict quality management system to ensure batch-to-batch consistency and high purity. Each lot undergoes comprehensive analytical testing, including gas chromatography (GC) for assay and impurity profiling. Certificates of Analysis (COA) documenting all test results are available upon request to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, well-ventilated area away from heat sources and incompatible materials. Due to its highly volatile nature, ensure containers are kept tightly sealed when not in use to prevent evaporation and maintain product integrity. Recommended storage temperature is 15-25°C.
