Abstract:
This invention provides a method that is capable of detecting a trifluridine-related substance and a tipiracil-related substance contained in a sample containing trifluridine or a salt thereof and tipiracil or a salt thereof using the same procedure. The method is for detecting a trifluridine-related substance or a tipiracil-related substance or both, the method comprising the step of subjecting a sample containing trifluridine or a salt thereof and tipiracil or a salt thereof to high-performance liquid chromatography using a mobile phase composed of an organic phase and an aqueous phase.

Claim (Index 19):
The method according to  claim 4 , wherein the difference between the maximum value and the minimum value of the percentage of the organic phase in the entire mobile phase at the retention times of the related substances 1, 3, and 4 and trifluridine is 5% by volume or less with respect to the entire mobile phase.
