Description

General description
Calconcarboxylic acid is a useful indicator for calcium titrations with EDTA in the presence of magnesium. It is also required for the staining of proteins in gels.
Calconcarboxylic acid is also known as Patton-Reeder indicator and is used in the determination of calcium at pH 12. Calconcarboxylic acid is a chelating agent and is used in the preparation of chelating sorbent along with chemically modified silica LiChroprep-NH₂, for trace metal analysis. Calconcarboxylic acid coupled with 3-aminopropyltriethoxysilane (APS-CCA), a fluorescent probe, facilitates the medical detection of Ca²⁺ ions in the blood with minimal blood backgrounds using hydrophobic hexadecyltrimethoxysilane (HDS) as substrate in fluorimetric microarray method.
Application
Calconcarboxylic acid (CCA) has been used in the preparation of poly-CCA film for leukemia diagnosis by immobilization, hybridization of DNA and detection by methylene blue and differential pulse voltammetry.
Analysis Note
Contains an inert diluent.
