Iminostilbene N-Carbonyl Chloride, identified by its CAS number 33948-22-0, is a cornerstone chemical compound within the pharmaceutical industry.

This compound, also known by synonyms such as Dibenz[b,f]azepine-5-carbonyl chloride, plays a pivotal role as a key intermediate in the synthesis of Carbamazepine. Carbamazepine is a widely recognized and essential medication used for managing conditions such as epilepsy, neuropathic pain, and bipolar disorder. The production of this life-saving drug heavily relies on the consistent supply of high-quality intermediates like Iminostilbene N-Carbonyl Chloride.

The chemical and physical characteristics of Iminostilbene N-Carbonyl Chloride contribute to its utility in complex synthesis processes. It typically appears as a white to yellow powder, a characteristic that assists in its identification and handling. With a molecular formula of C15H10ClNO and a molecular weight of approximately 255.70 g/mol, it is a moderately sized organic molecule. Its melting point, ranging from 149-153°C, and boiling point of around 413.7°C at 760 mmHg, indicate a significant degree of thermal stability, which is advantageous in chemical reactions that may involve elevated temperatures. These properties make it a reliable component for pharmaceutical intermediate synthesis.

The primary application of Iminostilbene N-Carbonyl Chloride lies in its function as a precursor for Carbamazepine. The synthesis process demands a high level of purity, often exceeding 95.0% assay, to ensure that the final pharmaceutical product meets rigorous regulatory standards. Manufacturers specializing in pharmaceutical intermediate production, particularly those in China, offer strategic sourcing advantages. These suppliers often provide competitive pricing and adhere to strict quality control measures, making them a preferred choice for global pharmaceutical companies looking to buy Iminostilbene N-Carbonyl Chloride.

Proper storage and packaging are also critical factors in maintaining the integrity of Iminostilbene N-Carbonyl Chloride. It is generally recommended to store the compound in a cool, well-ventilated environment, away from moisture and direct heat. Standard packaging often involves 25 kg drums, though customized packaging solutions are frequently available to meet specific client needs. This flexibility is a testament to the adaptability of suppliers in the fine chemical manufacturing sector.

In essence, Iminostilbene N-Carbonyl Chloride serves as a vital link between basic chemical compounds and advanced therapeutic solutions. Its consistent availability and quality are paramount for the continuous production of essential medicines. For businesses seeking reliable pharmaceutical intermediates, understanding the properties and sourcing of compounds like Iminostilbene N-Carbonyl Chloride is key to efficient drug development and manufacturing.
