More Information
Summary:The purpose of the present invention is to provide: a method for determining the presence or absence of an impurity in a mercapto heterocyclic compound using a simple process, and producing a refined (high purity) mercapto heterocyclic compound by, if an impurity is present, removing the same; and a test method for determining the presence or absence of an impurity in a mercapto heterocyclic compound using a simple process.　The present invention includes a method for producing a refined mercapto heterocyclic compound, the method comprising: a step (1) for obtaining a test solution by mixing an indicator reagent and a specimen which is obtained as a portion of a mercapto heterocyclic compound; a step (2) for observing the presence or absence of coloration of the test solution obtained in the step (1) and determining that an impurity is included in the mercapto heterocyclic compound when the same exhibits a color; and a step (3) for, if an impurity is determined to be included in the step (2), removing the impu
