For professionals in the pharmaceutical and fine chemical industries, understanding the specific properties and applications of key chemical compounds is fundamental to their work. Methyl 6-chloro-4-hydroxy-1,1-dioxo-2H-thieno[2,3-e]thiazine-3-carboxylate, identified by its CAS number 70374-51-5, is one such compound that holds significant importance.

Chemically, this molecule is a thienothiazine derivative. Its molecular formula is C8H6ClNO5S2, and it has a molecular weight of approximately 295.72 g/mol. A key characteristic highlighted in its specifications is its appearance: typically a light khaki powder. This physical state and color are important identifiers for quality control. Furthermore, its melting point range (often cited as 100-112°C or sometimes higher depending on purity and source) provides another benchmark for purity assessment.

The primary and most widely recognized application for CAS 70374-51-5 is its role as a crucial intermediate in the synthesis of Lornoxicam. Lornoxicam is a potent NSAID used for the management of pain and inflammation. The precise chemical structure of 70374-51-5 makes it an ideal precursor, allowing for efficient chemical transformations to construct the Lornoxicam molecule. This makes it an indispensable compound for manufacturers specializing in this therapeutic class.

Beyond its established role in Lornoxicam synthesis, this intermediate can also be a valuable component in broader organic synthesis and pharmaceutical research. Scientists and formulators may find its unique thienothiazine core structure useful for developing novel compounds or exploring new synthetic pathways. If you are a researcher or a procurement specialist looking to buy this compound for R&D purposes or for commercial production, understanding its specifications and typical applications is key.
