Girard's P reagent is a reagent used in organic chemistry. Girard's P reagent is used to react with vanillin to form a hydrazone derivative, which is then combined with an ion selective electrode (ISE) to develop a potentiometric method for the determination of vanillin. Girard's P reagent can be used in the development of ion selective electrodes and in the study of organic analysis.
