A protocol for determination of the content of dye in ? mixture for orange smoke grenades was proposed. The protocol was based on spectrophotometric determination of the dye 1.4- dihydroxyanthraquinone in DMSO solutions. The Beer’s law is obeyed in the concentration range of (0.5 -1.2) x10-5 mol/l dye with molar absorptivity 7.3x103 L/mol.cm. The protocol is very fast and show good accuracy (recovery 98.6 - 103.6 %) and precision (RSD 3.8%). The protocol was applied in model and real samples.
