dye

Methylene Blue trihydrate (Basic blue 9) is a compound consisting of dark green crystals or crystalline powder, having a bronze-like luster. Solutions in water or alcohol have a deep blue color. Methylene Blue trihydrate is used as a bacteriologic stain and as an indicator. It inhibits soluble guanylyl cyclase and has been used to treat cyanide poisoning and to lower levels of methemoglobin. It also inhibits tau filament formation (IC50: 1.9μM).

Pentetic Acid (Detarex) is an edetate and a chelating agent used in preparing radiopharmaceuticals.

Azure B (Azure B chloride) is a cationic dye and the major metabolite of Methylene blue. Azure B is a selective, and reversible inhibitor of MAO-A (IC50s: 11 and 968 nM for recombinant human MAO-A and MAO-B).

Ninhydrin is a chromogenic analytical probe for the quantification of proteins and amino acids.

Solvent Yellow 93, an azomethine dye, is used as a colorant of toner.

Brilliant blue G-250 (Acid blue 90, Coomassie Brilliant Blue G) is an antagonist of the P2X7 purinergic receptor.

Bromophenol Blue, an acid phthalein dye, is utilized both as a tracking dye for electrophoresis and as a pH indicator with a transition range of pH 3 to 4.6.

AMI5 (Eosin Y Disodium) is a soluble acidic red dye molecule. It is commonly used as a photoredox catalyst in organic synthesis.

Acid Yellow 36 (Metanil Yellow) is an azo dye and pH indicator, changing color from red at pH 1.2 to yellow at pH 2.3.

Ruthenium Red (Ammoniated ruthenium oxychloride) is a polycationic dye widely used for electron microscopy (EM) of cells, tissues and vegetative bacteria. Ruthenium red strongly reacts with phospholipids and fatty acids and binds to acidic mucopolysaccharides. Ruthenium red is a L-type calcium current (ICa) blocker, blocks Ca2+ uptake and release, and voltage-sensitive Ca2+ channels

Disperse Red 1 (Celliton Scarlet B) is an azo dye that contributes to the toxicity and pollution of wastewater.
