Methylene green zinc chloride double salt is a reactive dye that is used in biological and analytical methods. It has a high affinity for proteins, which allows it to be used as a marker for protein-dye interactions. The methylene green zinc chloride double salt is an optical sensor that changes color when the dye interacts with other substances. It can be used to detect the presence of pathogens, such as bacteria or viruses, by determining the amount of dye remaining after exposure to the pathogen. Methylene green zinc chloride double salt also reacts with tetrazolium dye in biological samples, such as human serum or brain tissue, to produce a color change. This reaction mechanism can be used to measure metabolic activity in cells and tissues. In wastewater treatment, methylene green zinc chloride double salt can be used as an adsorbent for removal of organic pollutants from water. Methylene green zinc chloride double salt also has radiation-blocking properties and can be used as a protective agent against radiation exposure

Applications As a dye for wool and silks; as colorant in food, drugs, and cosmetics. In biochemistry as an adsorption-elution indicator for chloride estimations. Tartrazine (otherwise known as E number E102, C.I. 19140, or FD&C Yellow 5) is a synthetic lemon yellow azo dye used as a food coloring. Tartrazine appears to cause the most allergic and intolerance reactions of all the azo dyes, particularly among asthmatics and those with an aspirin intolerance. Dyes and metabolites, Environmental Testing.A recent report has shown that Tartrazine may be useful in 3D bio-printing of organ-like architectures. References Rowe, K.S., et al.: J.

Direct Blue 202 is a reactive dye that is used in the treatment of wastewater. It has been shown to be effective for the removal of color from wastewater, with a high degree of efficiency. Direct Blue 202 has been shown to have low toxicity and does not persist in water. This dye also has dichroic properties and can be used as a polymerization initiator or coagulant.

Phenol red is a pH indicator that finds broad applications from chemistry to microbiology. Colour varies from yellow at pH<6.8 (lmax 443nm) through to light red/pink at 6.8<pH<8.2 (lmax 570 nm) to vivid purple/red at pH>8.2. It is widely used in cell culture to monitor pH and for colorimetric titration. For example, phenol red can be used to quantify Br- content in sea or fresh water. It is added to VTM as pH indicator, at the concentration of 10mg/ml, maintaining a pink colour at neutral pH.

Acid red 88 is a synthetic dye that has been used as a colorant in food, textiles and cosmetics. It is also used in wastewater treatment to remove organic pollutants from water. Acid red 88 has shown to be toxic to aquatic organisms, including fish and crustaceans. It has also shown to be highly adsorptive and stable in the environment. The hydrochloric acid-catalyzed conversion of Acid red 88 yields stable complexes with metals such as nickel, copper and zinc. These metal complexes are more resistant to degradation by biological treatment than other metal complexes with Acid red 88. Synchronous fluorescence spectroscopy showed that diazonium salt reacts with Acid Red 88 to form a diazo compound that can react with amines or ammonia gas to form an azoxy compound. This reaction can be catalyzed by activated carbon or detergent compositions containing an amine or ammonia gas.

C.I. Mordant Orange 6 is an alkanoic acid with a hydroxyl group and a sodium carbonate counter ion in the form of a coordination complex that is chemically stable in the presence of light and heat. The synthesis of this compound involves the reaction of 2-nitrobenzaldehyde with sodium hydroxylsulfonate followed by hydrolysis of the product with sodium carbonate. This synthetic process is used to produce C.I. Mordant Orange 6 in large quantities, which are then purified using chromatography or recrystallization techniques. The biological studies on C.I. Mordant Orange 6 have shown that it has antimicrobial properties, but it does not show cytotoxic effects against human cells in culture at concentrations up to 10 µg/mL, making it a potential candidate for use as an antimicrobial agent for applications such as food packaging materials.br>br>C.I. Mordant Orange 6 also has been shown to

D-102Dye is a cationic dye and drug repositioning agent that is used for the treatment of bacterial infections. This compound has been shown to be an active inhibitor of bacterial growth by binding to the surface glycoprotein and inhibiting the transport of nutrients into the cell. D-102Dye binds to the hydrophobic pocket on the outer membrane, forming hydrogen bonds with the phosphate groups found there. The electrochemical impedance spectroscopy studies have shown that this compound inhibits bacterial growth in logarithmic phase cells, but not in stationary phase cells. This may be due to its ability to bind to surface glycoproteins in these different phases. D-102Dye also has high affinity for monoclonal antibodies and methoxy groups, which are present on many proteins and enzymes in mammalian cells.

Pigment Yellow 12 is a yellow dye that belongs to the class of copper-complex dyes. It has a particle size of around 20 nm and an intramolecular hydrogen bonding with a hydroxyl group. Pigment Yellow 12 reacts with diazonium salt in the presence of hydrochloric acid, cationic surfactant, and amines to produce a bright yellow color. This dye is used as an indicator for urine samples, as well as in the production of textiles and plastics. Pigment Yellow 12 is not carcinogenic and does not have any known adverse effects on human health.
