For procurement managers and R&D scientists in the chemical and plastics industries, sourcing high-quality raw materials is a constant priority. One such critical material is 4-Hydroxy-2,2,6,6-tetramethyl-piperidinooxy, commonly known as 4-Hydroxy-TEMPO or Inhibitor 701, with CAS number 2226-96-2. This compound is a highly effective polymerization inhibitor, essential for preventing the unwanted self-polymerization of various monomers. If you are looking to purchase this vital chemical, understanding where to find reliable suppliers and what to look for is key.

China has emerged as a global hub for chemical manufacturing, offering a vast array of specialized compounds at competitive prices. When searching for 4-Hydroxy-TEMPO, it is crucial to identify manufacturers and suppliers who can consistently deliver a product with high purity, typically 99% or above. This purity is critical for ensuring the inhibitor's efficacy and preventing adverse reactions in sensitive monomer systems. The unique molecular structure of 4-Hydroxy-TEMPO allows it to effectively scavenge free radicals, thereby stabilizing monomers like acrylates, methacrylates, styrene, and butadiene during storage, transport, and processing.

When engaging with potential suppliers, always inquire about their manufacturing processes, quality control measures, and packaging standards. A professional supplier will readily provide a Certificate of Analysis (COA) detailing the product's specifications, including purity, moisture content, and appearance. For procurement managers, understanding the typical price range and minimum order quantities (MOQ) is also essential for effective budgeting and inventory management. The convenience of buying directly from China-based manufacturers often translates to significant cost savings, especially for bulk orders required in industrial-scale operations.

Beyond mere procurement, understanding the specific applications of 4-Hydroxy-TEMPO can help buyers pinpoint the best product grades. Its primary role as a polymerization inhibitor is vital for industries ranging from petrochemicals to fine chemicals. It ensures the stability of reactive monomers, preventing safety incidents and maintaining product integrity. For those requiring this chemical, a simple online search for 'buy 4-Hydroxy-TEMPO China' or 'CAS 2226-96-2 supplier' will yield numerous results. However, due diligence in verifying supplier credentials, product quality, and customer service is paramount. NINGBO INNO PHARMCHEM CO.,LTD., as a strategic supplier, can facilitate access to this and other essential fine chemicals, ensuring your supply chain is robust and reliable.

In conclusion, sourcing high-purity 4-Hydroxy-TEMPO from reputable Chinese manufacturers and suppliers is an achievable goal for businesses worldwide. By focusing on quality, purity, and reliable supply chains, buyers can secure this indispensable polymerization inhibitor and enhance the safety and efficiency of their operations.
