For Research & Development professionals in the chemical and materials science fields, understanding the fundamental science behind key additives is crucial for innovation and product development. Antioxidant 1010 (CAS 6683-19-8) represents a cornerstone in the field of stabilization, particularly for organic substrates susceptible to degradation.

Antioxidant 1010 is classified as a sterically hindered phenolic antioxidant. Its molecular structure features a pentaerythritol core esterified with 3-(3,5-di-tert-butyl-4-hydroxyphenyl)propionic acid. This steric hindrance around the phenolic hydroxyl group is key to its efficacy. It allows the antioxidant to efficiently donate a hydrogen atom to trap free radicals (like peroxy radicals) generated during oxidation, thereby terminating the auto-oxidation chain reaction. The resultant phenoxy radical is stabilized by resonance and the bulky tert-butyl groups, preventing it from initiating new degradation chains.

The primary mechanism involves radical scavenging, which is central to its role in preventing thermo-oxidative degradation. This makes it an essential additive when you buy Antioxidant 1010 for applications requiring long-term thermal stability. Its effectiveness is further amplified by its low volatility and excellent compatibility with a wide range of polymers and other organic materials. R&D scientists often explore its potential in synergistic blends with secondary antioxidants, such as phosphites or thioesters, to achieve comprehensive stabilization packages.

When considering the procurement of Antioxidant 1010, R&D teams should prioritize high purity levels (typically >95% or >99%) to ensure predictable reaction kinetics and performance outcomes.
