Objective To use purified water instead of the mobile phase containing methanol as diluent measure tinidazole sodium chloride injection content and related substances. Methods Hromatographic column:Amethyst C18-H, 150 mm×4.6 mm, 5μm. mobile phase:0.05 mol/L potassium dihydrogen phosphate solution-methanol water (20∶80) .flow rate : 1.0 mL/min, column temperature : 35℃, detection wavelength: 310 nm. Results Two determination result no significant difference. Conclusion Purified water instead of the mobile phase containing methanol as diluent convenient, safe, etermination result is accurate.
