On June 26, 2008, Brunner, Heiko; Dahms, Wolfgang; Grieser, Udo published a patent.Safety of 3-Amino-7-(diethylamino)-5-phenylphenazin-5-ium chloride The title of the patent was Preparation of halogenated or pseudohalogenated monomeric phenazinium compounds useful in acidic baths for electrolytically depositing copper.. And the patent contained the following:
Title compounds [I; R1, R2, R4, R7, R71, R8, R9 = H, halo, amino, aminoalkyl, OH, cyano, SCN, OCN, SH, CO2H, alkyl, (substituted) aryl, heteroaryl, etc.; R5 = alkyl, (substituted) aryl, heteroaryl; X = halo, pseudohalo; A- = acid anion], were prepared Thus, 3,7-diamino-2,8-dimethyl-5-phenylphenazinium chloride in 50% HBF4 at 50-60° was treated with aqueous NaSCN/NaNO2 over 1 h followed by stirring for an addnl. 1 h to give 64.0% 7-amino-2,8-dimethyl-3-thiocyanato-5-phenylphenazinium tetrafluoroborate. The latter in a Cu plating bath gave a brilliant, mirrorlike deposit without burns with invisible brush lines, indicative of an excellent leveling effect. The experimental process involved the reaction of 3-Amino-7-(diethylamino)-5-phenylphenazin-5-ium chloride(cas: 4569-86-2).Safety of 3-Amino-7-(diethylamino)-5-phenylphenazin-5-ium chloride
