The IUPAC name of Kayaku Fast Red 3GL Base is 4-chloro-2-nitroaniline. With the CAS registry number 89-63-4, it is also named as Azofix Red 3GL Salt. The product's categories are Intermediates of Dyes and Pigments; Anilines, Aromatic Amines and Nitro Compounds; Organics. It is bright orange powder which is insoluble in water, soluble in alcohol, ether and acetic acid, and slightly soluble in crude gasoline. It is also stable, combustible and incompatible with strong oxidizing agents. When heated to decomposition it emits toxic vapors of NOx and Cl−. What's more, this chemical can form explosive products on reaction with nitric acid. So the storage environment should be well-ventilated, low-temperature and dry. Keep Kayaku Fast Red 3GL Base separate from raw materials of food.
The other characteristics of this product can be summarized as: (1)ACD/LogP: 2.74; (2)# of Rule of 5 Violations: 0; (3)ACD/LogD (pH 5.5): 2.74; (4)ACD/LogD (pH 7.4): 2.74; (5)ACD/BCF (pH 5.5): 71.65; (6)ACD/BCF (pH 7.4): 71.65; (7)ACD/KOC (pH 5.5): 740.59; (8)ACD/KOC (pH 7.4): 740.59; (9)#H bond acceptors: 4; (10)#H bond donors: 2; (11)#Freely Rotating Bonds: 2; (12)Index of Refraction: 1.646; (13)Molar Refractivity: 41.92 cm3; (14)Molar Volume: 115.5 cm3; (15)Polarizability: 16.62×10-24 cm3; (16)Surface Tension: 62.2 dyne/cm; (17)Enthalpy of Vaporization: 54.95 kJ/mol; (18)Vapour Pressure: 0.000667 mmHg at 25°C; (19)Exact Mass: 172.003955; (20)MonoIsotopic Mass: 172.003955; (21)Topological Polar Surface Area: 71.8; (22)Heavy Atom Count: 11; (23)Complexity: 159.
Preparation of Kayaku Fast Red 3GL Base: It can be obtained by forcing ammonolysis of 2,5-Dichloronitrobenzene.
Uses of Kayaku Fast Red 3GL Base: It is used in the production of yellow pigment 10G, disperse yellow 211, UV absorber UV-326 and so on. It is not only used in dyeing cotton and printing cotton, but also used for dyeing of viscose fiber, silk and polyester. What's more, it can react with sulfuric acid dimethyl ester to get 4-chloro-N-methyl-2-nitro-aniline. This reaction which is a kind of methylation needs reagents NaOH, Bu4NHSO4 and solvent toluene, H2O at temperature of 20 °C. The yield is 100%.
