Some physical characteristics of this chemical are as the following: (1)ACD/LogP: 4.93; (2)ACD/LogD (pH 5.5): 1.43; (3)ACD/LogD (pH 7.4): 1.32; (4)ACD/BCF (pH 5.5): 1.03; (5)ACD/BCF (pH 7.4): 1; (6)ACD/KOC (pH 5.5): 3.61; (7)ACD/KOC (pH 7.4): 2.84; (8)#H bond acceptors: 7; (9)#H bond donors: 3; (10)#Freely Rotating Bonds: 4; (11)Polar Surface Area: 109.36.

This is soluble in ethanol. And it is blue in concentrated sulfuric acid and turns into Olive brown after diluting, with the appearance of purple sediment. This is irritant, so avoid contact with skin and eyes while dealing with it. Its product categories are various, including dyes and pigments; organics; aminoanthraquinones; anthraquinones; hydroxyanthraquinones. And its raw material is 1,4-Dihydroxyanthraquinone.

As to its usage, it is usually used in dyeing of wool and other wool products. Besides, it could also be used in dyeing and printing of silk, nylon, leater and other wool fabric. When comes to its making method, it is below: prepare the material of 1,4-Dihydroxyanthraquinone and Para Toluene, and then restore the 1,4-Dihydroxyanthraquinone to its leuco body; Then condense with Para Toluene and then go through the oxidation. Finally, sulfonate with fuming sulphuric acid and then neutralize, salting out, filtering, drying, and you could get the Acid Violet 43.
