Beschreibung

Pigment Red 144 is a dichroic, red pigment that absorbs light in the blue-green region of the spectrum. Its fluorescence emission peak is at 614 nm and it has a pH value of 1.0. Pigment Red 144 can be detected by titration with an inorganic acid, such as hydrochloric acid, or by spectrophotometric analysis using a standard curve prepared from an aromatic hydrocarbon. The chloride ion forms a salt with hydrogen chloride to produce glycol ethers and dichroic pigments. The particle size of the pigment ranges from 0.5 to 4 microns with detection sensitivity of 3 ppb.
