The present invention provides a method of measuring a component in blood, by which the amounts of blood cells and an interfering substance can be measured with high accuracy and high reliability and the amount of the component can be corrected accurately based on the amounts of the blood cells and the interfering substance. In a sensor for measuring a blood component, a first working electrode 13 measures a current that flows during a redox reaction of a blood component, a second working electrode 17 measures the amount of blood cells, and a third working electrode 12 measures the amount of an interfering substance. Next, based on the measurement results, the amount of the blood component to be measured is corrected. Thus, more accurate and precise measurement of the amount of the blood component can be realized.

The present invention provides a biosensor system that can prevent a measurement error caused by the temperature of the environment in use from occurring. A biosensor system 100 includes a measuring instrument 101 having an operation part 306, and a sensor chip 200 that is insertable into and removable from the measuring instrument 101 and into which a blood sample is introduced. The sensor chip 200 includes a measurement part 41 (a measurement part A) that acquires Data a related to the concentration of an analyte in a blood sample based on the amount of electric current that flows in the blood sample due to a reaction in which an oxidoreductase with the analyte used as a substrate is involved, and a measurement part 42 (a measurement part B) that acquires, from the blood sample, Data b for temperature correction of Data a. The operation part 306 has a function of determining the concentration of the analyte in the blood sample, with the concentration having been corrected according to the temperature of the blood sample based on Data a and Data b.

The first process includes the steps of (a) reacting a 2,2-bis(fluoromethyl)-6-(perfluoroalkyl)-2H-1-benzopyran-4-one with a perfluoroalkanesulfonic acid anhydride in the presence of a base, thereby obtaining a perfluoroalkanesulfonic 2,2-bis(fluoromethyl)-6-(perfluoroalkyl)-2H- 1-benzopyran-4-yl ester; and (b) reacting the benzopyranyl ester with carbon monoxide in the presence of a palladium complex compound and a base, thereby obtaining the carboxylic acid. The present invention further relates to a second process for producing a 2-hydroxy-5-(perfluoroalkyl) acetophenone, which can be a raw material for producing the carboxylic acid. The second process includes the steps of (c) reacting a 4-(perfluoroalkyl)alkoxybenzene with acetic anhydride or an acyl halide in the presence of a Lewis acid, thereby obtaining a 2-alkoxy-5-(perfluoroalkyl)acetophenone; and (d) dealkylating the 2-alkoxy-5-(perfluoroalkyl) acetophenone by a dealkylating agent.
