For any chemical procurement professional or R&D scientist, understanding the purity specifications of raw materials is a cornerstone of successful product development and manufacturing. Benzenesulfonamide (CAS 98-10-2) is no exception. As a crucial intermediate used in pharmaceuticals, dyes, and plasticizers, its purity directly impacts the efficacy, yield, and quality of the final products.

When you intend to buy Benzenesulfonamide, pay close attention to the assay value. A typical high-quality specification, as offered by manufacturers like NINGBO INNO PHARMCHEM CO.,LTD., indicates a minimum assay of 99.00%. Beyond the main compound percentage, critically important impurity levels include diphenyl sulfone, water, and free acid. Low levels of these impurities (e.g., ≤0.30% for diphenyl sulfone, ≤0.10% for water, and ≤0.20% for free acid) are essential for consistent performance in sensitive applications such as pharmaceutical synthesis.

The physical properties, like its solubility in ethanol and alkali, are also indicative of its quality and how it will perform in your specific chemical processes. Reliable suppliers in China are well-versed in these critical parameters and can provide detailed Certificates of Analysis (CoA) with each batch. Choosing a supplier that prioritizes these quality controls is paramount to avoiding costly production issues down the line.

Furthermore, understanding the Benzenesulfonamide price in relation to its purity and the supplier's quality assurance practices is vital. A slightly higher upfront cost for a highly pure product can often lead to significant savings in downstream processing and quality control. We encourage all potential buyers to inquire about our stringent quality control measures and request a sample to verify the purity and suitability of our Benzenesulfonamide for your needs. We are committed to being your trusted China-based manufacturer and supplier.
