Basic Rhodamine B for coloring specialty fireworks
Introduction
Basic Violet 10 commonly known as Rhodamine B or Basic Rhodamine B, is a triphenylmethane-based basic dye with strong fluorescence.
Physicochemical Properties
Basic Rhodamine B is easily identifiable due to its striking appearance and strong fluorescence.
Turns yellowish-brown with strong green fluorescence upon contact with concentrated sulfuric acid; upon dilution, turns bright red → blue-red → orange.
Aqueous solution with NaOH produces a rose-red color; heating produces a hairy precipitate.
Aqueous solution reacts with hydrochloric acid to precipitate fine green crystals.
