Product Grades
Polymer Grade
This is the highest purity grade, with a typical purity of ≥99.5%. It is specifically designed for the chemical synthesis of methacrylic acid (MAA) and methyl methacrylate (MMA). The strict control of impurities is critical to ensure the efficiency of the oxidation process and the quality of the final polymer products.
Industrial Grade
This grade has a slightly lower purity (e.g., ≥98.0%) and is used in various other industrial applications, such as the synthesis of specialty resins, fragrances, and pharmaceutical intermediates, where ultra-high purity is not the primary requirement.
Standard stock items are industrial grade. For special-grade orders, please contact us for full documentation.

Application of Methacrolein in Plastics & Polymers
Methacrolein is a pivotal intermediate in the plastics industry. Its primary use is in the production of methacrylic acid (MAA) via catalytic oxidation. MAA is then esterified to produce methyl methacrylate (MMA), the monomer for polymethyl methacrylate (PMMA), a transparent thermoplastic often used as a lightweight and shatter-resistant alternative to glass. It is also used to create various other acrylic resins and plastics with excellent optical clarity and weather resistance.
Application of Methacrolein in Pharmaceuticals
In the pharmaceutical sector, methacrolein serves as a versatile building block for the synthesis of complex organic molecules. Its reactive aldehyde and vinyl groups allow it to be used as a key intermediate in the production of various active pharmaceutical ingredients (APIs) and fine chemicals. It is involved in the synthesis pathways for certain vitamins, anti-inflammatory drugs, and other specialty therapeutic agents.
Application of Methacrolein in Flavors & Fragrances
Due to its potent and penetrating odor, methacrolein itself is not used directly in food. However, its derivatives are valuable in the fragrance industry. Through chemical modification, it can be converted into various acetals and other compounds that possess pleasant, often fruity or floral, aromas. These derivatives are used as scent components in perfumes, cosmetics, and other scented consumer products.
Application of Methacrolein in Agrochemicals
In the agrochemical sector, methacrolein acts as a critical synthetic intermediate for manufacturing crop-protection products. Its highly reactive aldehyde and carbon-carbon double-bond structures enable multi-step organic transformations. It serves as a foundational building block for several insecticides and herbicide intermediates. It participates in synthetic routes for selective agrochemical active substances, supporting the production of fine agrochemicals for crop disease and pest control.
Application of Methacrolein in Coatings & Adhesives
In the coatings and adhesives sector, methacrolein functions as a valuable chemical precursor for high-performance resin systems. Its reactive aldehyde and vinyl moieties facilitate polymerization and cross-linking reactions. It is an important intermediate for producing specialty acrylic-based polymers applied in industrial coatings and bonding formulations. It contributes to synthesis pathways for weather-resistant coating materials, high-strength adhesives, and other functional polymer products.
