For R&D scientists, procurement specialists, and formulation chemists, understanding the detailed specifications of pharmaceutical ingredients is paramount. Sulfamethazine (CAS 57-68-1), a vital antibacterial sulfonamide, is no exception. This article aims to provide a comprehensive overview of its purity, key specifications, and guidance on where to efficiently buy this crucial compound from reliable manufacturers and suppliers.

Understanding Sulfamethazine Specifications

Sulfamethazine, also known as Sulfadimidine, is chemically defined as 4-amino-N-(4,6-dimethylpyrimidin-2-yl)benzenesulfonamide. Its molecular formula is C12H14N4O2S, with a molecular weight of 278.33 g/mol. As a pharmaceutical-grade product, its specifications are rigorously defined to ensure efficacy and safety. Key parameters typically include:

  • Appearance: White to off-white crystalline powder.
  • Purity (Assay): A minimum of 99% is standard for high-quality Sulfamethazine. Pharmacopoeial grades (USP, BP, EP) often have even tighter controls.
  • Water Content: Usually specified as a maximum percentage, typically below 0.5%.
  • Related Substances: Limits on specific impurities are defined to ensure product integrity.
  • Identification: Confirmed through methods like IR or NMR spectroscopy.

Adherence to these specifications is crucial for its intended applications, whether in human or veterinary pharmaceuticals, or as a research chemical. As a dedicated manufacturer, we ensure our Sulfamethazine consistently meets these critical quality benchmarks.

The Importance of Purity in Pharmaceutical Applications

The purity of Sulfamethazine directly impacts its therapeutic effectiveness and safety profile. Impurities can lead to reduced efficacy, adverse reactions, or complicate formulation processes. Therefore, when you are looking to buy Sulfamethazine, it is essential to source it from manufacturers who implement stringent quality control measures throughout their production processes. This includes careful selection of raw materials, precise control of reaction conditions, and thorough analytical testing of the final product. A high assay percentage is often the first indicator of a premium product.
