Description

3-Methyl-2-Buten-1-Ol is a versatile, highly reactive allylic alcohol with a characteristic odor. This compound serves as a valuable chemical intermediate and building block in the synthesis of more complex molecules, particularly in the flavor, fragrance, and pharmaceutical sectors. It is essential for manufacturers requiring a high-purity, consistent raw material for the production of terpenoids, vitamins, and specialty chemicals.

Application

• Flavor and Fragrance (F&F) Industry: A key intermediate in the synthesis of terpene-based aroma chemicals, such as linalool and geraniol derivatives, used in perfumes, cosmetics, and food flavorings.
• Pharmaceutical Synthesis: Utilized as a building block for the production of active pharmaceutical ingredients (APIs) and vitamins, including Vitamin A and Vitamin E analogs.
• Agrochemical Manufacturing: Serves as a precursor in the synthesis of certain pesticides and plant growth regulators.
• Organic Synthesis: Acts as a versatile reagent in various organic reactions, including alkylation, esterification, and as a starting material for other allylic compounds.
• Polymer Chemistry: Can be used in the modification of polymers or as a monomer for specialty resins.

Quality Control

Our 3-Methyl-2-Buten-1-Ol is produced under a strict quality management system. Each batch undergoes rigorous analytical testing, including gas chromatography (GC), to ensure high purity and consistency. A comprehensive Certificate of Analysis (COA) detailing identity, assay, and impurity profiles is provided with every shipment. We can support compliance requirements for various industrial and specialty chemical applications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, well-ventilated place away from heat, sparks, and open flame. Due to its highly volatile and easily oxidized nature, it is recommended to store under an inert atmosphere (e.g., nitrogen) for long-term stability. Keep container tightly sealed when not in use to prevent evaporation and moisture absorption.
