Descriptions:
pubchem: Methacrylic acid is an alpha,beta-unsaturated monocarboxylic acid that is acrylic acid in which the hydrogen at position 2 is substituted by a methyl group. It is functionally related to an acrylic acid. It is a conjugate acid of a methacrylate.
chebi: An α,β-unsaturated monocarboxylic acid that is acrylic acid in which the hydrogen at position 2 is substituted by a methyl group.
chembl: METHACRYLIC ACID is a small molecule listed in the ChEMBL database but has not progressed to an approved clinical phase.
wikipedia: Methacrylic acid, abbreviated MAA, is an organic compound with the formula CH2=C(CH3)CO2H.  This colorless, viscous liquid is a carboxylic acid with an acrid unpleasant odor.  It is soluble in warm water and miscible with most organic solvents. Methacrylic acid is produced industrially on a large scale as a precursor to its esters, especially methyl methacrylate (MMA), and to poly(methyl methacrylate) (PMMA).
