For procurement specialists in the pharmaceutical industry, a thorough understanding of product specifications is non-negotiable. Lansoprazole (CAS 103577-45-3), a critical proton pump inhibitor, demands close attention to detail to ensure its efficacy and safety in final drug formulations. This article provides a breakdown of the key specifications and considerations when sourcing this vital pharmaceutical intermediate from reliable manufacturers, particularly those based in China.

The primary characteristic buyers look for in Lansoprazole is its purity. Reputable suppliers will typically guarantee an assay of 99.00-100.50% minimum. This high level of purity is essential for meeting regulatory requirements and ensuring the consistent therapeutic effect of the finished pharmaceutical product. The physical appearance of Lansoprazole is also a critical indicator of quality; it is commonly supplied as an off-white crystalline powder. Any deviation from this description can signal potential issues with manufacturing or storage.

Beyond purity and appearance, technical specifications such as water content (often specified as ≤5%) and melting point (typically 178-182°C dec.) are vital for formulators. These parameters influence the stability and processing of the API. When seeking to purchase Lansoprazole, inquiring about these specifications from potential suppliers is a standard practice. Manufacturers in China are increasingly competitive in offering high-quality Lansoprazole, making it an attractive option for global buyers looking for cost-effective solutions without compromising on quality.

Furthermore, understanding the application of Lansoprazole is crucial. It is primarily used as a pharmaceutical intermediate for the synthesis of medications that treat conditions like gastric ulcers, duodenal ulcers, and gastroesophageal reflux disease (GERD) by inhibiting gastric acid secretion. Buyers should also confirm the packaging standards (e.g., 20kg per fiber drum) and storage recommendations (e.g., 2-8°C) to ensure proper handling and preservation of the material. If you are in the market to buy Lansoprazole, engaging with a leading China manufacturer like TNJ Chemical can provide access to a reliable source of this essential pharmaceutical intermediate at competitive prices.
