4-Hydroxy-2,2,6,6-tetramethylpiperidine

Description:

4-Hydroxy-2,2,6,6-tetramethylpiperidine, commonly referred to as HTMP, is an organic compound characterized by its piperidine ring structure, which is substituted with four methyl groups and a hydroxyl group. This compound is notable for its role as a stable free radical scavenger and is often utilized in various applications, including as an antioxidant in polymers and as a stabilizer in plastics. The presence of the hydroxyl group contributes to its solubility in polar solvents, while the bulky tetramethyl substituents enhance its steric hindrance, which can influence its reactivity and stability. HTMP is typically a colorless to pale yellow liquid or solid, depending on its form, and it exhibits a relatively low volatility. Its stability under heat and light makes it particularly valuable in industrial applications, where it helps to prolong the lifespan of materials by preventing oxidative degradation. Safety data indicates that while it is generally considered to have low toxicity, appropriate handling and safety measures should be observed.
