Acid fuchsin is a water-soluble, non-toxic, acidic dye that is used in histology to stain connective tissue and mucous membranes. It is used as an indicator for calcium in the presence of acid phosphatase. Acid fuchsin can be detected by light microscopy when it is stained on a section of tissue or cells. This dye can be used with immunocytochemistry or cytogenetics to assess the morphology of cells and tissues. The staining intensity varies according to the concentration of the acid fuchsin solution, which can be quantified by measuring the absorbance at 510 nm. A reference range for this measurement would be 0.1 - 1 μg/ml (10 - 100 μM).

Bromocresol green is a dye that is used in biological assays to measure the kinetics of fluorescence. It is a type of tryptophan-releasing compound that releases a yellowish-green light when it absorbs light at wavelengths between 350 and 450 nm. Bromocresol green has been quantified by measuring the intensity of the fluorescence emission as a function of time. This can be done visually or using an instrument called a fluorometer, which detects changes in light intensity over time. Bromocresol green can be used to detect the presence of amino acid residues in proteins through protonation reactions with their tryptophan residues and subsequent quenching with acetonitrile. The bromocresol green dye is also used in lithographic printing, where it serves as an acceptor for electrons from an arene (aromatic hydrocarbon). This process generates energy for lithography and also provides contrast between regions with different electron densities.

Reactive Blue 19 is a chemical compound that has been used extensively in biological, biochemical, and clinical research. It is a reactive dye with the chemical formula C20H14N2Na4O8S4. The molecule's structure consists of two benzene rings linked by two amine groups, which are connected to an aromatic ring with four sulfonic acid side chains. Reactive Blue 19 has been shown to inhibit the activity of enzymes such as hydroxylase and nitrite reductase. This compound also reacts with protocatechuic acid to form an intense blue-colored complex that can be detected using electrochemical detection.

Acid Black ATT is a chemical compound that is used to adjust the pH and remove organic matter in wastewater. It is a mixture of trimethyl, collagen, sodium carbonate, calcium carbonate, and sodium chloride. Acid Black ATT can be used as an additive for the treatment of wastewater because it has been shown to inhibit enzymes. This product should be added slowly to water in order to avoid inhaling the vaporized acid. The use of this chemical must be carefully monitored because it can cause corrosion and damage to pipes.

Acid Orange 95 is a dye that is used in the textile industry. It is an orange-red liquid and has a pH of 2.0.

Acid blue 62 is a reactive dye that is used in the treatment of wastewater. It is used as a chemical intermediate to produce other dyes and as an ingredient in detergent compositions. Acid blue 62 has been shown to have genotoxic effects and may cause cancer. The potential for acid blue 62 to cause cancer is based on its chemical structure and its ability to form reactive metabolites with DNA, which can lead to the formation of DNA adducts. Acid blue 62 also has the ability to bind strongly to surfaces, which can lead to the formation of particulates or aggregates. The surface methodology suggests that the adsorption process follows a Langmuir adsorption isotherm. This means that there are two equilibrium constants, K1 and K2, where K1 > K2. The higher value of K1 indicates that adsorption will occur at low concentrations while high concentrations will cause desorption. This means that the particle size will increase with increasing concentration until it reaches
