Folkers and coworkers - found that when sufliciently pure concentrates of streptomycin were treated with methyl orange (the sodium salt of helianthine) a crystalline salt was formed with the sulfonic acid group of this dye. On recrystallization from aqueous methanol, pure streptomycin helianthate was obtained. The helianthate could be converted to streptomycin hydrochloride, sulfate or any other suitable salt for chemical or therapeutic purposes. All of these salts with the common inorganic acids are amorphous. They - also obtained a crystalline salt of streptomycin and p-(2-hydroxy-l-napthylazo)-benzenesulfonic acid from streptomycin hydrochloride and the azo dye Orange II. Streptomycin helianthate was converted directly into a crystalline streptomycin trihydrochloride-calcium chloride double salt. The chemistry of streptomycin was thus put on a crystalline basis.
