Description

Crotonaldehyde is a highly reactive, unsaturated aldehyde of significant industrial importance, primarily valued for its role as a versatile chemical intermediate. Its alpha,β-unsaturated carbonyl structure makes it a key building block for synthesizing a wide range of valuable compounds, from fine chemicals to polymers. This product is essential for manufacturers in the agrochemical, pharmaceutical, and specialty chemical sectors seeking reliable, high-purity raw materials for their synthesis processes.

Application

• Chemical Synthesis Intermediate: A crucial precursor for the production of sorbic acid, a widely used food preservative.
• Agrochemical Manufacturing: Used in the synthesis of various pesticides, herbicides, and plant growth regulators.
• Pharmaceutical Intermediates: Serves as a building block in the synthesis of specific active pharmaceutical ingredients (APIs) and vitamins.
• Resin and Polymer Production: Employed in the manufacture of certain synthetic resins, plasticizers, and rubber chemicals.
• Flavor and Fragrance Industry: Used in controlled quantities for the synthesis of specific aroma chemicals.
• Corrosion Inhibitors: Acts as an intermediate in the production of compounds used to protect metals.

Quality Control

Our Crotonaldehyde is manufactured under strict quality management systems to ensure batch-to-batch consistency and high purity. Each lot undergoes comprehensive analytical testing, including assay, impurity profiling, and physical property verification, to meet the stringent requirements of industrial synthesis. A Certificate of Analysis (COA) detailing all test results is provided with every shipment to guarantee full traceability and compliance with your specifications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, well-ventilated area away from heat sources, ignition points, and incompatible materials such as strong oxidizers, bases, and amines. Due to its highly volatile nature, containers must be kept tightly sealed when not in use to prevent evaporation and concentration of peroxides. Recommended storage temperature is 2-8°C (36-46°F) for extended stability.
