Description

Ethyl Crotonate is a versatile and highly volatile ester of crotonic acid, valued for its role as a key chemical intermediate and flavor/fragrance component. Its reactivity and distinct organoleptic properties make it a critical building block in the synthesis of more complex molecules. This compound is essential for manufacturers in the flavors & fragrances, agrochemicals, and pharmaceutical industries seeking reliable, high-purity raw materials.

Application

• Flavor and Fragrance Ingredient: Used as a synthetic flavoring agent and fragrance component, imparting fruity, sweet, or wine-like notes to food products, beverages, and perfumes.
• Chemical Synthesis Intermediate: Serves as a crucial building block in organic synthesis, particularly in Michael addition reactions and the production of other esters, pharmaceuticals, and fine chemicals.
• Agrochemical Production: Employed in the manufacturing of certain pesticides, herbicides, and plant growth regulators due to its reactive ester functionality.
• Polymer Modification: Acts as a monomer or co-monomer in specialty polymerizations to modify resin properties, such as flexibility and adhesion.
• Solvent and Extraction Agent: Utilized as a specialty solvent in specific laboratory and industrial processes where its volatility and solvency power are advantageous.
• Research & Development: A valuable reagent in academic and industrial R&D labs for exploring new synthetic pathways and material science applications.

Quality Control

Our Ethyl Crotonate is produced under stringent quality management systems to ensure batch-to-batch consistency and high purity. We offer grades suitable for flavor/fragrance (FEMA) and industrial synthesis applications. Each batch is supported by a comprehensive Certificate of Analysis (COA) detailing purity, identity, and impurity profiles, available upon request to meet your compliance and safety documentation needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, well-ventilated area away from heat sources and open flames. 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 2-25°C.
