  • Applications

    2-(N-Hydroxy-C-undecylcarbonimidoyl)-4-methylphenol (CAS 50652-76-1) is used primarily as an antioxidant and stabilizer in polymers and related formulations, with its lipophilic undecyl substituent promoting compatibility with nonpolar plastics and rubbers to inhibit thermo-oxidative degradation in polyolefins, polyurethanes, and elastomer systems. It is commonly evaluated for use in coatings and inks to enhance color stability and resistance to heat and light, and in lubricant formulations as an oxidation stabilizer and radical-scavenging additive. The compound can also function as a stabilizing additive in adhesives and sealants, helping extend service life under aging conditions in multi-material assemblies. Subject to local regulations and formulation limits, 2-(N-Hydroxy-C-undecylcarbonimidoyl)-4-methylphenol is typically selected where long-term oxidative stability is required in nonpolar or low-polarity matrices.
