Bathocuproinedisulfonic acid disodium salt (CAS 52698-84-7)

Bathocuproinedisulfonic acid disodium salt, with the CAS number 52698-84-7, is a specialized chemical compound used extensively as a chelating agent in analytical chemistry, particularly in the quantification and detection of divalent metal ions such as copper(II). This compound belongs to the broader family of cuproine derivatives and is highly soluble in water due to its disulfonic acid groups, which enhances its utility in various aqueous systems. The primary mechanism of action of bathocuproinedisulfonic acid disodium salt involves the formation of a strong complex with copper ions, characterized by a distinct and intense color change, typically resulting in an orange-colored chelate. This reaction is highly specific and sensitive, making it an excellent tool for photometric assays where precise measurement of copper concentrations is required, such as in environmental water samples or biological fluids. In research contexts, this compound has been utilized in studies that investigate copper′s role in environmental systems and its biogeochemical cycles. Additionally, its specificity for copper has made it valuable in studies examining copper′s impact on ecological health and in processes that require the removal or recovery of copper from industrial effluents. The ability of bathocuproinedisulfonic acid disodium salt to form stable complexes with copper also facilitates its use in electrochemical sensors and other devices aiming to detect and quantify metal ions with high precision. This reagent, therefore, not only serves fundamental analytical purposes but also contributes significantly to environmental monitoring and management strategies.
