The backbone of many advanced chemical products, from life-saving pharmaceuticals to vibrant pigments, is the reliable availability of high-purity intermediates. Among these, 2-Aminobenzenesulfonamide (CAS 3306-62-5) stands as a compound of significant interest for researchers and industrial chemists alike. This article explores its role in chemical synthesis and offers insights for procurement professionals looking to buy this essential material.

The Chemical Profile of 2-Aminobenzenesulfonamide

2-Aminobenzenesulfonamide is an organic compound characterized by an amine group (-NH2) and a sulfonamide group (-SO2NH2) attached to a benzene ring at ortho positions. Its molecular formula is C6H8N2O2S, and it typically presents as a white to off-white crystalline powder. The key properties that make it valuable for synthesis include its distinct functional groups, which allow for a range of chemical transformations. Its melting point, generally falling between 153-157 °C, is a standard specification used by many manufacturers.

As a crucial intermediate, it serves as a foundational element in several synthetic pathways:

  • Pharmaceutical Synthesis: Most notably, it is a precursor for sulfa drugs, a class of antimicrobial agents. The synthesis often involves modifying the amino or sulfonamide groups to create active pharmaceutical ingredients (APIs).
  • Dye Synthesis: It acts as a coupling component or diazo component in the formation of azo dyes, contributing to a wide spectrum of colors.
  • Organic Synthesis: Beyond these primary applications, it can be utilized in the synthesis of various heterocyclic compounds and other specialty chemicals, depending on the research or industrial objective.

The Imperative of Purity for Synthesis

In any chemical synthesis, the purity of starting materials dictates the success and efficiency of the process. For 2-Aminobenzenesulfonamide, particularly when used in pharmaceutical manufacturing, sourcing a product with a high assay, such as 98% or 99% minimum purity, is critical. Impurities can interfere with reaction mechanisms, lead to the formation of undesired byproducts, and compromise the quality of the final synthesized compound. Therefore, when you purchase this intermediate, always seek detailed specifications and Certificates of Analysis (COA) from your supplier.

Finding Quality 2-Aminobenzenesulfonamide from China

China is a significant global producer of chemical intermediates. For businesses looking to buy 2-Aminobenzenesulfonamide, partnering with a reputable Chinese manufacturer or supplier can offer both quality and cost advantages. Key factors to consider when selecting a supplier include:

  • Quality Assurance: Verify their quality control processes and product testing.
  • Technical Support: A good supplier will offer technical data and assistance.
  • Logistics and Supply Chain: Ensure they can reliably deliver the required quantities.
  • Competitive Pricing: Compare quotes to find the best value for your budget.
