Cuprizone is a copper chelating agent that forms a deep blue copper ketone complex with copper (II). The copper ketone reaction can be used in colorimetric tests for the presence of trace copper. Cuprizone can be used to induce some schizophrenia-like behavior in mice. Cuprizone acts on copper enzymes, including SOD1, cytochrome oxidase, and DβH, thereby causing oxidative stress and increasing DA levels in certain brain regions such as the medial prefrontal cortex (PFC) .

Bathocuproine disulfonate disodium (BCS) is an organic compound used as a highly sensitive colorimetric reagent for copper ions in biochemical and analytical applications. It has a bright yellow color and absorbs light at specific wavelengths, so it can be used to detect and quantify trace copper. In biochemical applications, BCS is commonly used to study the role of copper ions in various biological processes. Copper is an essential nutrient for many organisms, but it can also be toxic in high concentrations, so accurate measurement of copper levels is important to understand its impact on living systems. In terms of analysis, BCS is often used in environmental monitoring and water quality testing to detect copper pollution. It can detect copper even at very low concentrations, making it an invaluable tool for identifying potential sources of pollution and assessing the impact of industrial activities on aquatic ecosystems.

Synonyms: CPRG
Chlorophenol red-β-D-galactopyranoside (CPRG) is an efficient and sensitive chromogenic substrate for β-galactosidase (HY-P2869), widely used in colorimetric assays. Chlorophenol red-β-D-galactopyranoside itself appears pale yellow. When it is specifically hydrolyzed by β-galactosidase, it releases chlorophenol red. The released chlorophenol red turns purple-red under alkaline or neutral pH conditions. This color change from yellow to red can be quantitatively detected at wavelengths of 540-572 nm using visible spectrophotometry .

TBHBA (2,4,6-Tribromo-3-hydroxybenzoic acid) is a chemical colorimetric agent and nanomaterial surface modifier. TBHBA can react with some oxidants (such as H2O2) to generate high-absorbance quinoneimine dyes, which enhance the sensitivity of HDL cholesterol enzymatic determination. TBHBA can be used as a bromine-containing coupling agent to modify the surface of silica nanoparticles through esterification reaction. Thereby, organic flame retardant groups are introduced to improve the thermal stability and flame retardant properties of nanocomposites. TBHBA can be used in clinical biochemical testing (such as serum lipoprotein analysis) and the preparation of flame-retardant polymer nanocomposites .
