In the demanding field of pharmaceutical manufacturing, every chemical component, especially an intermediate, must meet stringent specifications. 4-Amino-5-chloro-2,1,3-benzothiadiazole (CAS: 115398-34-0) is no exception. As a key precursor in the synthesis of important pharmaceuticals like Tizanidine hydrochloride, understanding its precise characteristics—from appearance to purity and optimal storage—is crucial for procurement managers and R&D scientists. As a dedicated 4-Amino-5-chloro-2,1,3-benzothiadiazole manufacturer, we prioritize these details to ensure client success.

The typical appearance of this compound is a white crystalline powder. This physical characteristic is just the first step in quality assurance. More importantly, its chemical specifications are rigorously controlled. A purity level of ≥99% is a standard requirement, reflecting the need for minimal impurities in pharmaceutical synthesis. Moisture content is also critical, typically kept below 0.1%, to prevent degradation and ensure consistent reactivity. Furthermore, the overall impurity level is controlled to be ≤0.5%, a vital parameter for regulatory compliance and the safety of the final API.

Understanding the storage requirements for 4-Amino-5-chloro-2,1,3-benzothiadiazole is essential for maintaining its quality. It should be stored in a cool, dry, well-closed container, shielded from moisture, strong light, and excessive heat. This practice preserves the compound's stability and shelf-life, ensuring that it remains fit for purpose over time. For businesses looking to buy this intermediate, inquiring about recommended storage conditions from their 4-Amino-5-chloro-2,1,3-benzothiadiazole supplier is a best practice.

The competitive landscape often drives pharmaceutical companies to seek out reliable 4-Amino-5-chloro-2,1,3-benzothiadiazole manufacturers, particularly in regions like China, known for their robust chemical production capabilities. When you aim to purchase this chemical, evaluating a supplier's commitment to these specifications—purity, low moisture, controlled impurities, and appropriate packaging (e.g., 25kg cardboard drums)—is key. A transparent supplier will readily provide Certificates of Analysis (CoA) to verify these attributes, assuring you of the product's quality and suitability for your critical pharmaceutical syntheses.

In summary, the efficacy and safety of pharmaceuticals directly depend on the quality of their building blocks. 4-Amino-5-chloro-2,1,3-benzothiadiazole, with its defined specifications and critical role in API synthesis, requires careful sourcing. By partnering with experienced manufacturers and paying close attention to purity, storage, and supplier credentials, you can ensure the success of your pharmaceutical development and production endeavors.
