What Is Another Name for Methacrylic Acid? Quick Answer
CAS No. 79-41-4 Methacrylic acid (MAA) is also known as methacrylic acid or 2-methyl-2-acrylic acid. MAA is a colorless transparent liquid at room temperature. Melting point 14°C. Boiling point 159-163°C (100KPa), flash point 77°C. Soluble in hot water, ethanol and most organic solvents. Easy to polymerize.
Methacrylic acid is an important chemical raw material. It can be used to prepare methyl methacrylate, coatings, synthetic rubber, adhesives, fabric treatment agents, resins, polymer material additives and functional polymer materials.
Other Names: 2-methylpropenoic acid, 2-methylacrylic acid, 2-Propenoic acid, 2-methyl-, MAA.
Why Does Methacrylic Acid Have Several Names?
Chemical compounds often have multiple names because different naming systems serve different purposes.
- Methacrylic Acid is the internationally recognized common name used by manufacturers and suppliers.
- MAA is the widely accepted abbreviation in the coatings, resin, and polymer industries.
- 2-Methylpropenoic Acid is the official IUPAC name that precisely describes the molecular structure.
- Registry databases and customs documents may use names such as 2-Propenoic acid, 2-methyl-, but these refer to the same substance.
Recognizing these naming conventions can help buyers avoid confusion when sourcing materials from different countries or suppliers.

What is methacrylic acid (MAA CAS 79-41-4) used for?
- The main use of methacrylic acid is its polymerization to poly(methyl methacrylate).
- It is used in some nail primers to help acrylic nails adhere to the nail plate.
- Copolymers consisting partially of methacrylic acid are used in certain types of tablet coatings in order to slow the tablet's dissolution in the digestive tract, and thus extend or delay the release of the active ingredient.

Frequently Asked Questions
Q: What is Methacrylic Acid mainly used for in industrial production?
A: It is mainly used as a monomer to produce methyl methacrylate (MMA) and various acrylic polymers, which are widely applied in paints, coatings, adhesives, and plastic materials.
Q: Is Methacrylic Acid safe to handle during transportation and storage?
A: MAA is a flammable and reactive chemical, so it must be stored with inhibitors, kept in a cool and ventilated place, and transported according to hazardous chemical regulations.
Q: What purity level is usually required for industrial use?
A: Most industrial applications require ≥99.0% or 99.5% purity, depending on whether it is used for resins, coatings, or pharmaceutical-related materials.
Q: Can Methacrylic Acid be mixed with water?
A: Yes, it is partially soluble in water, but it mixes more easily with alcohols and many organic solvents.
Q: What should buyers check before purchasing Methacrylic Acid?
A: Buyers should confirm CAS number (79-41-4), purity, inhibitor content, packaging type, and COA/MSDS documents to ensure product quality and compliance.
Summary
In summary, Methacrylic Acid (MAA, CAS 79-41-4) is a key industrial monomer known by several alternative names such as 2-methylpropenoic acid and 2-methylacrylic acid. Despite the different naming conventions, they all refer to the same chemical compound widely used in acrylic resins, coatings, adhesives, plastics, and pharmaceutical materials. Understanding its properties, safety requirements, and correct identification is essential for both technical users and chemical buyers.
