For chemists, formulators, and procurement specialists in the chemical industry, understanding the precise technical specifications of a compound is fundamental to its effective application. 4-Oxo-TEMPO (CAS 2896-70-0), a highly regarded free radical polymerization inhibitor, is no exception. As a seasoned manufacturer and supplier in China, we provide detailed insights into its properties, applications, and the crucial aspects to consider when sourcing this vital chemical.

Understanding the Technical Profile of 4-Oxo-TEMPO

4-Oxo-TEMPO is recognized for its molecular formula C9H16NO2 and a molecular weight of approximately 170.23 g/mol. Its most distinctive characteristic is its role as a stable nitroxyl radical, which is key to its function as a polymerization inhibitor.

Key technical specifications typically include:

  • CAS Number: 2896-70-0 - The universally recognized identifier for this compound.
  • Appearance: Commonly described as an orange powder, solid, or crystals. This visual cue is the first indicator of product quality.
  • Purity: High purity levels are critical for optimal performance. We typically offer 4-Oxo-TEMPO with a purity of ≥ 98% (GC) or even higher, ensuring minimal interference from impurities. For specialized applications, higher purity grades may be available upon request.
  • Melting Point: Typically in the range of 33-38 °C. This parameter is indicative of the compound's physical state and purity.
  • Water Content: Generally kept very low, often below 0.2%, as excess moisture can affect stability and performance.
  • Assay: The quantification of the active ingredient, usually stated as a percentage (e.g., 98% MIN).

Applications Driven by Technical Properties

The technical attributes of 4-Oxo-TEMPO directly translate into its effectiveness in various applications, most notably:

  • Polymerization Inhibition: Its free radical scavenging ability makes it ideal for preventing the spontaneous polymerization of monomers like acrylates, methacrylates, acrylic acid, acrylonitrile, styrene, and butadiene. This is crucial during monomer production, purification, storage, and transportation.
  • Industrial Synthesis: It can be used to control and regulate the degree of polymerization in organic synthesis reactions involving olefins and their derivatives.
