• • • • • • • • • Product Overview

                  Copper sulfate pentahydrate (CAS 7758-99-8) is a bright blue crystalline powder or granular solid with the molecular formula CuSO₄·5H₂O and a molecular weight of 249.68 g/mol. It is one of the most widely used copper salts, readily soluble in water and forming acidic solutions. The product is supplied at a minimum purity of 99.0% and has a wide range of applications including agricultural fungicides, electroplating, textile dyeing, and as a reagent in chemical synthesis and analytical chemistry. This reagent-grade product is manufactured under strict quality control and is available in 500g laboratory bottles and 25kg industrial bags.

                  Synthetic Process

                  Copper sulfate pentahydrate is primarily produced by the reaction of copper metal or copper oxide with dilute sulfuric acid in the presence of air. The resulting solution is concentrated, crystallized, and dried to obtain the pentahydrate form. The product can also be obtained from copper-containing ores through leaching and crystallization processes. The pentahydrate form is the most common and stable form at room temperature.

                  Mechanism of Action / Application Principles

                  As a fundamental chemical reagent, copper sulfate pentahydrate functions through several key mechanisms:

                  • Copper Ion Source: It serves as a convenient source of copper ions (Cu²⁺) for various chemical reactions, including the preparation of other copper compounds and coordination complexes.

                  • Catalyst: Copper sulfate is used as a catalyst in numerous organic reactions, including oxidation, coupling, and cyclization reactions.

                  • Bactericide/Fungicide: In agriculture, it is used as a fungicide and bactericide, often in formulations such as Bordeaux mixture for crop protection.

                  • Analytical Reagent: It is used in analytical chemistry as a reagent for the detection and determination of various substances, including as a component of Fehling‘s solution for reducing sugar detection
