The IUPAC name of Methacrylic acid is 2-methylprop-2-enoic acid. With the CAS registry number 79-41-4, it is also named as 2-Methylenepropionic acid. The classification codes are Drug / Therapeutic Agent and Mutation data. It is colourless liquid or crystals with an unpleasant odour which is soluble in warm water and miscible with most organic solvents. Methacrylic acid is corrosive to metals and tissue and may polymerize exothermically if heated or contaminated. If the polymerization takes place inside a container, the container may rupture violently. It is flammable, so people should keep it away from oxidants and bases. Additioanlly, this chemical should be sealed in the container and stored in the cool, ventilate and dry place.

Preparation of Methacrylic acid: It can be obtained by the two-step oxidation of isobutylene. First oxidation to get methacrolein and second oxidation to get methacrylic acid. And then we can get qualified products by distillation.
CH₂=C(CH₃)CH₃+O₂→CH₂=C(CH₃)CHO+H₂O
CH₂=C(CH₃)CHO+ 1/2O₂→CH₂=C(CH₃)COOH

Uses of Methacrylic acid: It is used in the manufacture of paints, insulation materials, adhesives, and ion exchange resins. It is also used as important organic chemical raw material and polymer intermediate. Methacrylic acid is organic reagent. In addition, it can react with oxirane to get methacrylic acid-(2-hydroxy-ethyl ester). This reaction needs reagents water and triethylamine  at temperature of 125 °C. 

When you are using this chemical, please be cautious about it as the following:
