Pigment Red 21
CAS:Pigment Red 21 is a primary amine that has a liquid crystal composition. It is used as a pigment in paints and plastics, and can be found in deionized water. Pigment Red 21 has a diameter of 10 nm and the structural formula C12H17N3O5. It is an inorganic pigment with chelate ligand functional groups. Pigment Red 21 is also known as Scarlet, FD&C Red No.21, or E120. This pigment absorbs radiation from the electromagnetic spectrum and converts it to heat energy, which causes its color change from red to orange when heated above its melting point of about 250 degrees Celsius. The thermal expansion coefficient for this product is approximately 4x10^-6/K at 25 degrees Celsius.Formula:C23H16ClN3O2Purity:Min. 95%Color and Shape:PowderMolecular weight:401.84 g/mol
