Abstract:
The present invention provides a novel method that is capable of detecting a trifluridine-related substance from a sample containing trifluridine or a salt thereof by high-performance liquid chromatography comprising two steps that are performed under gradient conditions. More specifically, the method is for detecting a trifluridine-related substance, the method comprising the step of subjecting a sample containing trifluridine or a salt thereof to high-performance liquid chromatography using a mobile phase composed of an organic phase and an aqueous phase, wherein the step of high-performance liquid chromatography comprises steps 1 and 2 that satisfy the following requirements: Step 1: the percentage of the organic phase in the entire mobile phase is 1 to 14% by volume; and Step 2: after step 1, elution is performed by applying a gradient of increasing the percentage of the organic phase in the entire mobile phase.

Claim (Index 8):
The method according to  claim 1 , wherein, in step 2, the elution is performed by applying a gradient of increasing the percentage of the organic phase in the mobile phase by 0.9% by volume or more per 1 minute.
