How data was acquired	Elite_La Chrom HPLC (VWR/HITACHI, Milan, Italy/Tokyo, Japan) apparatus equipped with a L-2130 high pressure quaternary gradient delivery system, a L-2455 diode array detector (DAD), a L-2300 column oven and a L-2200 autosampler. The separation was achieved on a XBridgeTM column (4.6 mm × 150 mm, 5 μm) (Waters).
Data format	Analyzed.
Experimental factors	100 mg of domiphen bromide/p-bromodomiphen bromide dissolved in 2 mL of 1 M NaOH at 80 °C for 48 h.
	100 mg of domiphen bromide/ p-bromodomiphen bromide bromide dissolved in 2 mL of 2 M HCl at 80 °C for 48 h.
	100 mg of domiphen bromide/ p-bromodomiphen bromide in 2 mL of HPLC-grade water at 100 °C for 4 days.
	100 mg of domiphen bromide/ p-bromodomiphen bromide dry at 100 °C for 4 days.
Experimental features	HPLC analyses; chromatograms extracted at 220 nm.
