Thermo Scientific™ Methacrylic Acid (MAA) 99.5% Stabilised is a high-purity, inhibitor-protected monomer widely used in polymer production, specialty chemical synthesis, coatings, adhesives, resins, and advanced materials research. Supplied as a clear, extra-pure liquid, the product is stabilised with approximately 250 ppm MEHQ (4-methoxyphenol) to prevent premature polymerization and ensure safe storage and long-term stability.

With exceptional purity verified by GC ≥99.4%, tightly controlled color (≤20 APHA), and excellent physical consistency, this reagent is suitable for high-precision laboratory work, industrial R&D, and manufacturing-scale processes.
