Methacrylic acid is a colorless liquid organic compound with a sharp, acrid odor. It is primarily used in the production of polymers and resins, which are essential in various applications, including coatings, adhesives, and plastics. The compound is known for its ability to polymerize, forming strong and durable materials. This acid is produced through the esterification of acrylic acid and methanol. It is also a key ingredient in the manufacture of methacrylate monomers, which are used to create materials like acrylic glass and dental products. Safety precautions are necessary when handling methacrylic acid due to its corrosive nature.
