Formation of methyl ester of salicyluric acid during quantitation of salicyluric acid in urine by high-pressure liquid chromatography.
The formation of the methyl ester of salicyluric acid was observed during the quantitation of salicyluric acid and other salicylate metabolites in urine by high-pressure liquid chromatography. This methyl ester formation caused artificially low values for salicyluric acid and high values for salicylic acid.
