Description
DIAMINE GREEN B is a dark green to deep purple powder that is soluble in water, acetone, and soluble fiber elements. It has limited solubility in alcohol and is insoluble in other organic solvents. The dye solution exhibits color changes when exposed to strong acids, turning violet black in strong sulfuric acid and purple in strong hydrochloric acid and nitric acid. It also forms a dark blue light green precipitation when exposed to strong hydrochloric acid. The dye has good affinity for cellulose fiber and is sensitive to discharge, with copper and iron ions turning the dye dark colored.
Uses
Used in Textile Industry:
DIAMINE GREEN B is used as a dye for cellulose fibers, such as cotton and hemp, due to its good dye devouring properties and highest affinity at 80°C. It is also used in the dyeing and printing of cotton and viscose fabrics, as well as silk, polyamide fiber, stick/hair, and sticky/Kam fabric.
Used in Paper Industry:
DIAMINE GREEN B is used for shading in the paper industry, providing a dark green to deep purple color to the paper.
Used in Soap Industry:
DIAMINE GREEN B is used in the soap industry to impart a dark green to deep purple color to the soap products.
Used in Leather Industry:
DIAMINE GREEN B is used in the leather industry for shading, adding a dark green to deep purple color to the leather products.
Used in Manufacture of Color Pigment Sediment:
DIAMINE GREEN B is also used in the production of color pigment sediment, contributing to the dark green to deep purple color of the pigment.

Check Digit Verification of cas no
The CAS Registry Mumber 4335-09-5 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,3,3 and 5 respectively; the second part has 2 digits, 0 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 4335-09:
(6*4)+(5*3)+(4*3)+(3*5)+(2*0)+(1*9)=75
75 % 10 = 5
So 4335-09-5 is a valid CAS Registry Number.
