Description

General description

Ammonium metavanadate is an ammonium salt. It participates as an oxidizing agent for condensation reaction of o-phenylenediamine with substituted aryl aldehydes.

Application

Ammonium metavanadate may be employed in the following studies:

• As catalyst for the synthesis of various 2-substituted aryl benzimidazoles.
• As oxidizing agent in the determination of chlorpromazine, promethazine, trimeprazine and perphenazine in pharmaceutical samples by flow injection method.
• Synthesis of dioxidovanadium(V) complex.
• Preparation of Vanadia modified titania (V₂O₅/TiO₂) photo-catalysts.
