Usage and Safety

Application

Bis(ethylenediamine)copper(II) hydroxide has been used to evaluate cation exchange capacity (CEC) of clays by copper absorption.Copper(II) ethylenediamine complex may be used to evaluate the cation exchange capacity (CEC) of clay materials. It may also be used to modify polyoxoniobate, which is a class of polyoxometalates (POMs) that finds potential application in photocatalytic H₂ production.

Copper(II) sulfate pentahydrate can be used as a catalyst:

In acetylation of alcohols and phenols in the presence of acetic anhydride.
To synthesize various ynamides via intramolecular coupling of amides with 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.

Copper(II) sulfate pentahydrate may be employed in the following studies:

As a catalyst for the acetylation of alcohols and phenols under solvent-free conditions.
To compose the electrolyte for the electrodeposition of Cu-Zn-Sn precursors, required for the preparation of Cu₂ZnSnS₄ (CZTS) thin films.
As catalyst for the dehydration of alcohols.

Determination of main fruits in adulterated nectars by ATR-FTIR spectroscopy combined with multivariate calibration and variable selection methods.: This study highlights the application of ATR-FTIR spectroscopy, a technique involving Copper(II) sulfate pentahydrate, in identifying fruit content in adulterated nectars, illustrating its relevance in food chemistry and quality control (de Souza SVC et al., 2018).

Measurement of electron paramagnetic resonance using terahertz time-domain spectroscopy.: This research demonstrates the use of terahertz time-domain spectroscopy, involving Copper(II) sulfate pentahydrate, to measure electron paramagnetic resonance, contributing to advancements in spectroscopic methodologies (Hangyo M et al., 2011).

Effects of Curcuma xanthorrhiza Extracts and Their Constituents on Phase II Drug-metabolizing Enzymes Activity.: Though indirectly related, this article explores the role of natural extracts on enzyme activity, providing a context where Copper(II) sulfate pentahydrate could be used as a comparative standard in bioanalytical settings (Ab Halim MR et al., 2016).
