The realm of fine chemicals is replete with intricate molecules that form the backbone of modern advancements, particularly in the pharmaceutical sector. Among these, 10-Methoxy-4H-benzo[4,5]cyclohepta[1,2-b]thiophen-4-one, identified by its CAS number 59743-84-9, stands out as a significant compound. Its complex fused ring structure, featuring a thiophene and a benzene ring, augmented by a methoxy group at the 10-position and a carbonyl group at the 4-position, endows it with unique chemical properties highly valuable in organic synthesis. As a key intermediate, its role in the efficient creation of pharmacologically active molecules is undeniable.

For procurement specialists and research chemists, understanding the physical and chemical properties of CAS 59743-84-9 is essential. Typically presented as a yellow powder, its molecular formula C14H10O2S and molecular weight of 242.29 g/mol are fundamental identifiers. Information regarding its density (1.32 g/cm³) and boiling point (436.4 °C at 760 mmHg) provides further context for handling and reaction design. However, the most critical specification for its use as a pharmaceutical intermediate is its purity, often stipulated at ≥99.0% by reputable suppliers. This level of purity is crucial for ensuring the efficacy and safety of downstream products, such as the antihistamine Ketotifen.

The primary application in organic synthesis for this compound is its use as a precursor in the production of Ketotifen. This makes it a sought-after chemical for pharmaceutical companies and contract manufacturing organizations (CMOs). Researchers involved in developing new drug candidates or optimizing existing synthesis routes may also find this heterocyclic compound of interest due to its reactive functionalities. When looking to purchase 10-Methoxy-4H-benzo[4,5]cyclohepta[1,2-b]thiophen-4-one, buyers often search for competitive price of C14H10O2S from reliable manufacturers. Partnering with a dedicated supplier of CAS 59743-84-9 intermediate, especially one based in China with proven manufacturing capabilities, can significantly streamline the procurement process.
