Cas no 59804-25-0 (Methyl 4-Hydroxy-2-methyl-2H-Thieno2,3-e-1,2-thiazine-3-carboxylic Acid 1,1-Dioxide Ester)

Methyl 4-Hydroxy-2-methyl-2H-Thieno[2,3-e]-1,2-thiazine-3-carboxylic Acid 1,1-Dioxide Ester is a heterocyclic sulfonamide derivative with a thienothiazine core structure. This compound exhibits notable reactivity due to the presence of both hydroxyl and ester functional groups, making it a versatile intermediate in organic synthesis. The 1,1-dioxide moiety enhances its stability and potential for further functionalization. Its structural features suggest utility in pharmaceutical and agrochemical research, particularly in the development of bioactive molecules. The methyl ester group improves solubility in organic solvents, facilitating downstream reactions. Careful handling is recommended due to potential sensitivity to hydrolysis under acidic or basic conditions.
