Specification

The DirectBlue151 is an dyestuff with the molecular formula C₃₄H₂₅N₅O₁₀S₂.2Na. The systematic name of this chemical is (3E)-3-(2-{4'-[(2E)-2-(6-amino-1-oxo-3-sulfonaphthalen-2(1H)-ylidene)hydrazinyl]-3,3'-dimethoxybiphenyl-4-yl}hydrazinylidene)-4-oxo-3,4-dihydronaphthalene-1-sulfonic acid. With the CAS registry number 110735-25-6, it is also named as Azine Copper Blue 2B; Benzo Copper Blue CVBS. In addition, it is blue black powder which appears blue purple when dissolved in water and appears reddish purple when soluble in alcohol.

The other characteristics of this product can be summarized as: (1)ACD/LogP: 0.53; (2)# of Rule of 5 Violations: 3; (3)ACD/LogD (pH 5.5): 0; (4)ACD/LogD (pH 7.4): 0; (5)ACD/BCF (pH 5.5): 1; (6)ACD/BCF (pH 7.4): 1; (7)ACD/KOC (pH 5.5): 1; (8)ACD/KOC (pH 7.4): 1; (9)#H bond acceptors: 15; (10)#H bond donors: 6; (11)#Freely Rotating Bonds: 10; (12)Index of Refraction: 1.721; (13)Molar Refractivity: 183.406 cm³; (14)Molar Volume: 463.776 cm³; (15)Polarizability: 72.708×10^-24 cm³; (16)Surface Tension: 68.204 dyne/cm.

Preparation of DirectBlue151: Using dianisidine, J acid and NW acid as the basic raw materials; Diazotizating dianisidine with sodium nitrite and sulfuric acid; Neutralizing J acid and NW acid with sodium hydroxide; And then coupling the diazotization material and salts of J acid and NW acid, and finally by salting out, filtration and drying, we can get the product.

Uses of DirectBlue151: It is mainly used to dye cotton, linen, rayon and other cellulose fiber, and also used for coloring viscose / nylon blended fabric. In addition, it can be used for dyeing leather and paper.
