2-Hydroxyethyl methacrylate(CAS: 868-77-9)

2-Hydroxyethyl methacrylate (HEMA), CAS 868-77-9, is a clear, colorless liquid monomer used in polymer chemistry. Its chemical formula is C5H10O3, featuring a methacrylate group and a hydroxyethyl chain. HEMA is highly reactive, soluble in water and organic solvents, and hygroscopic. It is commonly used as a building block for polymers due to its ability to form hydrophilic networks. Its properties make it valuable in applications requiring adhesion and flexibility.

2-Hydroxyethyl methacrylate (HEMA) is widely used in pharmaceuticals for drug delivery systems and hydrogel coatings. In industry, it serves as a monomer in adhesives, coatings, and composite materials. It is also employed in biomedical applications, such as dental resins and contact lenses, due to its biocompatibility. Additionally, HEMA is used in research for polymer synthesis and functional material development. Its versatility stems from its ability to polymerize and crosslink with other compounds.

2-Hydroxyethyl methacrylate (HEMA) is generally considered safe when handled properly. It has low acute toxicity but may cause skin or eye irritation. Safety standards, such as OSHA and EU regulations, require appropriate protective measures, including gloves, goggles, and ventilation. Prolonged exposure should be avoided, and it is classified as a potential irritant. Always follow safety guidelines to minimize risks during use and storage.

2-Hydroxyethyl methacrylate (HEMA) should be stored in a cool, dry place (≤25°C), away from light and moisture. Keep in tightly sealed, airtight containers to prevent degradation. Avoid contact with air and humidity to maintain stability. Store in a well-ventilated area to reduce vapor exposure. Proper storage ensures safety and prolongs the shelf life of this reactive chemical.
