Pigment Yellow 180 is a yellow pigment with a boiling point of 116°C. It has a viscosity of 0.5-1.0 Pa·s, an aliphatic hydrocarbon content of less than 10%, and an iron content of less than 1%. Pigment Yellow 180 is soluble in acetone, ethyl acetate, benzene, toluene, and xylene. Pigment Yellow 180 has been used as a colorant in paints and plastics and is composed of calcium carbonate (CaCO3), synthetic process, hydroxyl group, diameter, particle size

Pigment Red 210 (PR210) is a chemical with an orange-red color. PR210 is a hydroxyl compound with a glycol ether and glycol ester as the major components. It has been used as a control agent for plasma mass spectrometry. PR210 has good chemical stability and does not react with nitrogen atoms. It is also a molecule that consists of particles with a diameter of about 1 micrometer. The radiation from this pigment can cause allergic reactions in some people, and it may be toxic if inhaled or ingested because it can cross-link proteins in the body. PR210 was first synthesized in the 1930s by reacting phenol with 2,4-dichloro-1,3-benzenediol to produce hydroquinone monomethyl ether and 2,4-dichloro-1,3-benzenediol monomethyl ether. The reaction products are then mixed in an acid solution

Fast Violet B is a diazonium salt that reacts with an amine, such as phosphatase, to release hydrogen. This reaction can be used to measure the activity of phosphatases. The emission of light in the visible range depends on the concentration and pH of the solution. Fast Violet B is soluble in water, alcohol, acetone, ether and chloroform. It has a particle size that ranges from 0.1-0.2 microns in diameter and will not dissolve in most solvents. Fast Violet B can be used to detect zearalenone in animal feed samples using a sample preparation technique called thin layer chromatography (TLC). It has shown clinical utility for determining antibody response in humans by measuring fatty acid synthesis activity during the inflammatory response. Fast Violet B also reacts with hydrogen bonds between nucleotides on DNA molecules and it binds to human mitochondrial DNA because it contains many phosphate groups and several intramolecular hydrogen bonds can form between neighboring

Applications Sethoxydim is a neuroplastin isoforms, a member of Ig superfamily. It is expressed and important in stereocilia of outer hair cells function. Also, it is derived from Crotonaldehyde (C818650), which is an αβ-unsaturated aldehyde and an alkylating agent that is commonly found in tobacco smoke and some foods. Crotonaldehyde is also a known mutagen and carcinogen. References Zeng, W., et al.: J. Neurosci., 36, 9201-9216 (2016); Scherer, G., et al.: Hum. Exp.
