The synthesis of active pharmaceutical ingredients (APIs) is a complex, multi-step process where the quality and availability of intermediates directly impact the final product. Famotidine, a potent H2 receptor antagonist used to treat conditions like heartburn and peptic ulcers, is one such API where specific intermediates play a critical role. Among these, (S)-((2-Guanidino-4-thiazolyl)methylisothiourea dihydrochloride, identified by CAS number 88046-01-9, stands out as a crucial building block.

As a dedicated manufacturer and supplier of pharmaceutical intermediates, NINGBO INNO PHARMCHEM CO.,LTD. understands the significance of this compound. (S)-((2-Guanidino-4-thiazolyl)methylisothiourea dihydrochloride serves as a key precursor, contributing essential structural elements that are later modified to form the complete Famotidine molecule. Its precise chemical structure, featuring a thiazole ring and guanidine groups, is strategically incorporated into the developing API.

The synthesis pathway often involves reacting this intermediate with other reagents to build the side chains and functional groups characteristic of Famotidine. The purity of the (S)-((2-Guanidino-4-thiazolyl)methylisothiourea dihydrochloride is paramount. Impurities present in the intermediate can lead to unwanted side reactions, reduced yields, or the formation of difficult-to-remove byproducts in the final Famotidine API. This underscores the importance of procuring this chemical from a reliable source that guarantees high purity, typically above 95% and often exceeding 99% as specified by rigorous quality control protocols.

Researchers and production managers often search for terms like 'famotidine intermediate supplier' or 'buy CAS 88046-01-9' when initiating their procurement processes. NINGBO INNO PHARMCHEM CO.,LTD. serves as a leading manufacturer in China, providing this essential intermediate with a commitment to quality and consistency. Our advanced synthesis capabilities ensure that we can deliver this compound reliably, supporting both R&D scale experiments and large-scale commercial production.

The structural integrity of (S)-((2-Guanidino-4-thiazolyl)methylisothiourea dihydrochloride is vital for the stereochemical outcome of the Famotidine synthesis. While the provided sources indicate the presence of the (S)-enantiomer, confirming the enantiomeric purity can be an important consideration for specific applications or regulatory requirements. For those looking to purchase pharmaceutical intermediates, understanding these subtle yet critical aspects is key.

In essence, the role of (S)-((2-Guanidino-4-thiazolyl)methylisothiourea dihydrochloride in Famotidine synthesis cannot be overstated. It is a foundational component that directly influences the efficiency, purity, and ultimately, the efficacy of the final drug product.
