Description

General description

Copper(II) sulfate pentahydrate is a blue colored crytal known as blue vitrol. It is highly soluble in water and methanol whereas it is insluble in ethanol and acetone. Copper(II) sulfate pentahydrate is commonly used in various applications such as agriculture, electroplating, and as a laboratory reagent. It is widely use in developing low-cost and efficient electrocatalysts for applications such as water splitting, which is essential for the production of hydrogen as a clean fuel.

Application

• Copper(II) sulfate pentahydrate can be used as a precursor
• To synthesis of Molecular organic framwork (MOF) with benzene-1,3,5-tricarboxylic acid via solvothermal synthesis. This metal-organic framework (MOF) used as a heterogeneous catalyst for the biodiesel production with high yield
• To synthesis of Ni foam film-supported CoCu alloy microspheres composed of nanosheets which act as a catalyst for the hydrolysis of ammonia borane. The catalyst has exhibited stability and reuseability.
• Copper(II) sulfate pentahydrate can be used as a catalyst:
• In acetylation of alcohols and phenols in the presence of acetic anhydride.
• Many different copper-based compounds have been studied as catalysts in Copper-Catalyzed Azide-Alkyne Cycloaddition (CuAAC) using Cu(II) species such as Copper sulphate pentahydrate.
• Catalyst for the synthesis of macrocyclic ynamides via intramolecular amidation of alkynyl Bromides.
• It can also be used as a template in the synthesis of copper(II) ion-imprinted polymers using vinylpyridine and methacrylic acid as functional monomers. This polymer is used to quantify Cu²⁺ ion by using flame atomic absorption spectroscopy.

Features and Benefits

• Medium purity with trace metals basis
• Inexpensive
• Safe catalyst
• Reuseability is high
