5850-35-1 Usage
Description
ACID BLUE 29, also known as C.I. 20460, is an organic dye that is used for coloring purposes. It is characterized by its navy blue color and is soluble in water and ethanol. When exposed to strong sulfuric acid, it emits a blue light, and upon dilution, it forms a greenish-blue precipitate. The dye is also known to have good light fastness, soaping fastness, and perspiration fastness, making it suitable for various applications.
Uses
Used in Textile Industry:
ACID BLUE 29 is used as a dye for coloring fabrics, particularly those that require a navy blue color. Its solubility in water and ethanol makes it easy to apply, and its good fastness properties ensure that the color remains vibrant even after multiple washes and exposure to sunlight.
Used in Water Treatment:
ACID BLUE 29 is also recognized as a water pollutant and can be removed from water using photocatalytic degradation. This application is crucial in the treatment of industrial wastewater, where the removal of harmful dyes is essential for environmental protection.
Used in Analytical Chemistry:
The dye's properties make it useful in analytical chemistry for various tests and experiments. For instance, its color change in the presence of acids and bases can be utilized to determine the pH of a solution.

Check Digit Verification of cas no
The CAS Registry Mumber 5850-35-1 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,8,5 and 0 respectively; the second part has 2 digits, 3 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 5850-35:
(6*5)+(5*8)+(4*5)+(3*0)+(2*3)+(1*5)=101
101 % 10 = 1
So 5850-35-1 is a valid CAS Registry Number.
