NMT 7.0 Endotoxins unit/mg of Ranitidine as per SOP
12.0 Related substance: Determine by liquid chromatography.
Test solution: -Dilute a volume of the injection with water to obtain 0.1 per cent w/v of Ranitidine.
Reference solution (a) Dilute 1.0 ml of the test solution to 50.0 ml with water.
Reference solution (b) Dilute 1.0 ml of the test solution to 100.0 ml with water.
Reference solution (c) Dilute 1.0 ml of the test solution to 200.0 ml with water.
Reference solution (d) Dilute 1.0 ml of reference (b) to 5.0 ml with water.
Reference solution (e) Dissolve the content of a vial of Ranitidine impurity J RS in 1.0 ml of a 0.013 percent w/v solution of ranitidine hydrochloride RS in water.
Buffer: – 0.05M potassium dihydrogen phosphate. 1000 ml water. adjust to pH 7.1
With Sodium hydroxide.
Mobile phase (A): – A mixture 2 volume of acetonitrile and 98 volume of Buffer.

Inject reference solution(e) the test is not valid unless the resolution between two principal peak is not less than 1.5
Inject reference solution(a), (b), (c), (d) and the test solution in the chromatogram obtained with the test solution the area of any secondary peak is not more than the principal peak in the chromatogram obtained with the reference solution (a) (2.0 percent). The area of not more than one secondary peak is more than the area of principal peak in the chromatogram obtain with the reference solution (b) (1.0 percent) The area of not more than two other secondary peak is more than the area of principal peak in the chromatogram obtained with reference solution (c) (0.5 percent) and the area of not more than two further secondary peak is more than the area of principal peak in the chromatogram obtained with reference solution (d) (0.2 percent).
