Description

Methyl Vinyl Ketone CAS NO 78-94-4 is a highly reactive, low molecular weight α,β-unsaturated ketone, serving as a critical building block in organic synthesis. Its value lies in its bifunctional nature, featuring both a reactive carbonyl group and a polymerizable vinyl group, enabling a wide range of chemical transformations. This compound is essential for manufacturers in the pharmaceutical, agrochemical, and specialty polymer industries seeking to synthesize complex intermediates, active ingredients, and functional materials.

Application

• Pharmaceutical Intermediates: A key precursor in the synthesis of steroids, prostaglandins, and various heterocyclic compounds with biological activity.
• Agrochemical Synthesis: Used in the production of pesticides, herbicides, and plant growth regulators.
• Polymer & Resin Manufacturing: Acts as a cross-linking agent and comonomer for acrylic resins, specialty adhesives, and coatings to enhance properties like hardness and chemical resistance.
• Chemical Synthesis: Employed in Michael addition reactions, Robinson annulations, and Diels-Alder reactions to construct complex carbon skeletons.
• Flavor & Fragrance Industry: Serves as an intermediate for synthesizing certain aroma chemicals.
• Research & Development: A versatile reagent in academic and industrial R&D labs for exploring new synthetic pathways.

Quality Control

Our Methyl Vinyl Ketone is manufactured under stringent process controls to ensure batch-to-batch consistency and high purity. Quality is verified through comprehensive analytical testing including Gas Chromatography (GC) and titration methods. A Certificate of Analysis (COA) detailing purity, identity, and impurity profiles is provided with each shipment, ensuring compliance with your specific project requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, well-ventilated area 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) and at temperatures between 2°C and 8°C for extended stability. Keep away from strong oxidizing agents, bases, and reducing agents.
