Puzanowska-Tarasiewicz, Helena et al. published their research in Acta Poloniae Pharmaceutica in 1990 | CAS: 316-81-4

N,N-Dimethyl-10-(3-(4-methylpiperazin-1-yl)propyl)-10H-phenothiazine-2-sulfonamide (cas: 316-81-4) belongs to piperazine derivatives. Industrial applications of piperazine include the manufacture of plastics, resins, pesticides and brake fluids. Outside the body, piperazine has a remarkable power to dissolve uric acid and producing a soluble urate, but in clinical experience it has not proved equally successful. Product Details of 316-81-4

Extractive-spectrophotometric determination of phenothiazine derivatives as compounds with picramic acid was written by Puzanowska-Tarasiewicz, Helena;Regulska, Ewa;Kleszczewska, Ewa. And the article was included in Acta Poloniae Pharmaceutica in 1990.Product Details of 316-81-4 This article mentions the following:

Promazine, chlorpromazine, and thioproperazine were extracted from. aqueous solutions with a CHCl3 solution of picramic acid as 1:1 associates The drugs were determined in the extracts by spectrophotometry at 500 nm in concentrations of 8-80, 25-250, and 16-160 μg/mL concentrations, resp. The average error did not exceed 1.12%. In the experiment, the researchers used many compounds, for example, N,N-Dimethyl-10-(3-(4-methylpiperazin-1-yl)propyl)-10H-phenothiazine-2-sulfonamide (cas: 316-81-4Product Details of 316-81-4).
