2-Anthracenesulfonic acid, 1-amino-4-[(3-aminophenyl)amino]-9,10-dihydro-9,10-dioxo-, also known as CI Direct Blue 6, is a complex organic compound with the chemical formula C20H15N3O5S. It is a type of anthraquinone dye, characterized by its blue color and high solubility in water. 2-Anthracenesulfonic acid, 1-amino-4-[(3-aminophenyl)amino]-9,10-dihydro-9,10-dioxo- is widely used in the textile industry for dyeing cotton, wool, and silk, as well as in paper and leather applications. It is known for its excellent colorfastness and resistance to light and washing. However, due to its potential environmental and health concerns, its use is regulated in many countries, and efforts are being made to find more sustainable alternatives.

6685-75-2 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 6685-75-2 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,6,8 and 5 respectively; the second part has 2 digits, 7 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 6685-75:
(6*6)+(5*6)+(4*8)+(3*5)+(2*7)+(1*5)=132
132 % 10 = 2
So 6685-75-2 is a valid CAS Registry Number.

Method for isolating albumin using insoluble supports coupled to a dye

-

, (2008/06/13)

A method for the isolation of albumin which allows the selective adsorption and substantially quantitative elution of albumin from mixtures containing the same. The method comprises contacting a solution which contains albumin with a member of a series of dye-insoluble support compounds in which the insoluble support is a polyhydroxy polymer coupled to a dye by means of a reactive pyrimidine. The albumin which is selectively adsorbed can be readily eluted resulting in essentially a quantitative recovery of pure albumin.
