Description

Pigment Red 49 is a diazonium salt that has been used as a dye in many areas of industry. The red color can be obtained by reacting pigment red 49 with sodium salts, hydrochloric acid, and ethylene diamine. Pigment Red 49 is also used in clinical studies to detect the presence of nitrogen atoms. This substance can cause allergic reactions and is classified as a particle. It has also been found to have an effect on radiation and glycol esters. Pigment Red 49 interacts with cationic surfactants, which are compounds that have a cationic charge due to the presence of at least one quaternary ammonium group. Pigment Red 49 is soluble in fatty acids and glycol esters.
