We report here for the first time two potentiometric carbon-paste sensors for determination of thiamine chloride hydrochloride in aqueous solutions. The proposed sensors use the ion-pair of thiamine with tetraphenylborate as an electro-active species

8-Acetyl-7-hydroxy-4-methyl coumarin and 3-amion-1,2,4-triazole were used to prepare a Schiff base (Sbat). The [Ag(Sbat)(NO3)]·H2O and [Cu(Sbat)(OH)(H2O)2]·3H2O complexes were separated by the reaction of the Schiff base with Ag(I) and Cu(II) metal
