(57) Abstract: strong single in MRI singlet 19 F 19 F-MRI that gives a signal and has tissue selectivity Provide compounds useful for diagnostic clinical applications. SOLUTION: The following general formula: R c NHR f (where R c is a sugar acyl residue having tissue selectivity, R f is: —CH 2 C (CF 3 ) 2 OR 1 , — (CH 2 ) k ACH m (CH 2 ECONHR) 3-m or-(CH 2 ) k ACH m (CH 2 ECONHCH p (CH 2 E ') CONHR) 3-p ) represents 3-m . A) a fluorine-containing sugar derivative represented by the formula (1), a contrast agent containing the derivative as an essential component, a production intermediate thereof, and a production method. |
