4-Hydroxy-2-methyl-2H-1,2-benzothiazine-3-carboxylic Acid, 1,1-Dioxide could be useful in analytical studies that look to enhance chemical stability of drug substances with high melting points by melt extrusion. 4-Hydroxy-2-methyl-2H-1,2-benzothiazine-3-carboxylic Acid, 1,1-Dioxide is similar to Methyl 4-Hydroxy-2-methyl-2H-1,2-benzothiazine-3-carboxylate 1,1-Dioxide (M312845(P)), which is an impurity found in Meloxicam (M216100(P)). Meloxicam was specifically used in these melt extrusion studies.
