Methacrylic acid (MAA) is a versatile organic compound that exists as a colorless, viscous liquid. It serves as a monofunctional methacrylate monomer and possesses solubility in warm water, as well as miscibility in most organic solvents. Methacrylic acid holds significant importance as a starting material for the production of various esters, particularly methyl methacrylate and poly methyl methacrylate (PMMA). Chemically, methacrylic acid is categorized as an alpha,beta-unsaturated monocarboxylic acid, representing an acrylic acid with a methyl group substitution at position 2. Its origin can be traced back to acrylic acid, and it functions as the conjugate acid of a methacrylate.
