Reported in EPA TSCA Inventory.
The IUPAC name of Magenta is 4-[(4-aminophenyl)-(4-imino-3-methylcyclohexa-2,5-dien-1-ylidene)methyl]aniline hydrochloride . With the CAS registry number 632-99-5, it is also named as Benzeneamine, 4-((4-aminophenyl)(4-imino-2,5-cyclohexadien-1-ylidene)methyl)-2-methyl-, monohydrochloride ; Fuchsin, basic ; Astra fuchsine B ; Basic Fuchsine (VAN) ; Diabasic magenta ; Orient basic magenta ; Rosaniline chloride ; Rosaniline hydrochloride ; Fuchsine SBP .
The Magenta is green crystal powder which is slightly soluble in water. It is a dye derived from triphenylmethane. As a dye, it can be used for dyeing of cotton, acrylic, silk and leather. It is also used for coloring of paper, feathers, straw, bamboo and wood. Magenta may be incompatible with isocyanates, halogenated organics, peroxides, phenols (acidic), epoxides, anhydrides, and acid halides. It can neutralize acids in exothermic reactions to form salts plus water. In addition, it may generate hydrogen, a flammable gas, in combination with strong reducing agents such as hydrides. It also can easily reduced to colorless leuco-bases .
The Magenta is probably combustible. When heated to decomposition it emits very toxic fumes of HCl and NOx. It is harmful if swallowed. There is limited evidence of a carcinogenic effect. Keep container tightly closed and keep away from sources of ignition. If you want to contact this product, you must wear suitable protective clothing and gloves.
The Magenta can be obtained by the following mwthod. 1. Melting aniline, p-toluidine and o-toluidine and nitrobenzene, ferrous chloride together; 2. Oxidation and condensation; 3. Using sulfate extraction; 4. Neutralize, salting-out, filtration and drying; 5. Getting the product.
The other characteristics of this product can be summarized as: (1)ACD/LogP: 0.88 ; (2)# of Rule of 5 Violations: 1 ; (3)#H bond acceptors: 3 ; (4)#H bond donors: 5 ; (5)#Freely Rotating Bonds: 4 ; (6)Enthalpy of Vaporization: 89.58 kJ/mol ; (7)Vapour Pressure: 3.55E-14 mmHg at 25°C ; (8)Rotatable Bond Count: 2 ; (9)Tautomer Count: 7 ; (10)Exact Mass: 337.134575 ; (11)MonoIsotopic Mass: 337.134575 ; (12)Topological Polar Surface Area: 75.9 ; (13)Heavy Atom Count: 24 ; (14)Complexity: 515.
People can use the following data to convert to the molecule structure. SMILES: Cl.Nc1ccc(cc1)C(c2cc(C)c(N)cc2)=C3C=CC(=N)C=C3; InChI: InChI=1/C20H19N3.ClH/c1-13-12-16(6-11-19(13)23)20(14-2-7-17(21)8-3-14)15-4-9-18(22)10-5-15;/h2-12,21H,22-23H2,1H3;1H.
