Description

Butanoic Acid 3-Methyl-2-Butenyl Ester is a specialized ester compound valued for its unique organoleptic and chemical properties. This product serves as a versatile intermediate and flavor/fragrance component in high-value manufacturing processes. It is primarily sought by producers in the flavor & fragrance, pharmaceutical intermediates, and specialty chemical synthesis sectors for its specific molecular structure.

Application

• Flavor and Fragrance Ingredient: Used as a building block or modifier in the creation of fruity, green, or herbal aroma profiles for perfumes, cosmetics, and personal care products.
• Pharmaceutical Intermediate: Acts as a key synthon in the multi-step synthesis of active pharmaceutical ingredients (APIs) and other bioactive molecules.
• Specialty Chemical Synthesis: Employed in organic synthesis as a reagent or precursor for producing more complex esters, fine chemicals, and agrochemical intermediates.
• Food Flavoring Agent: When produced to appropriate purity standards (e.g., FCC), it can be used as a synthetic flavoring substance in food and beverage applications.
• Research and Development: Serves as a standard or starting material in chemical R&D for studying esterification reactions and property modifications.

Quality Control

Our Butanoic Acid 3-Methyl-2-Butenyl Ester is produced under a strict quality management system. Each batch undergoes comprehensive analytical testing to ensure identity, purity, and consistency. We provide Certificates of Analysis (COA) with key parameters including assay, specific gravity, and refractive index. Specifications can be tailored to meet FCC, USP, or custom purity requirements for various industrial applications.

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 easily oxidized nature, it is recommended to store under an inert atmosphere (e.g., nitrogen) for long-term preservation of quality, especially after opening. Recommended storage temperature is 2-25°C.
