Description
Acid Violet 49, also known as Benzyl Violet, is a fine black powder with bright blue-purple color. It is a product from the degradation of methyl green and is an impurity of α,α-Bis[4-(dimethylamino)phenyl]-4-(methylamino)-benzenemethanol. Acid Violet 49 is easily soluble in cold and hot water, resulting in a purple color, and is also soluble in ethanol. When exposed to strong sulfuric acid, it turns orange, and when diluted, it takes on a mustard color. The addition of sodium hydroxide solution results in dark precipitation.
Uses
Used in Textile Industry:
Acid Violet 49 is used as a dye for wool, silk, and polyamide fiber dyeing. It is known for its good spelling color performance.
Used in Food Industry:
After being refined, Acid Violet 49 can be used as a dye in the food industry.

Reactivity Profile
Acid Violet 49 neutralizes acids in weakly exothermic reactions to form salts plus water. May be incompatible with isocyanates, halogenated organics, peroxides, phenols (acidic), epoxides, anhydrides, and acid halides. May generate hydrogen, a flammable gas, in combination with strong reducing agents such as hydrides.
Hazard
Possible carcinogen.

Check Digit Verification of cas no
The CAS Registry Mumber 1694-09-3 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,6,9 and 4 respectively; the second part has 2 digits, 0 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1694-09:
(6*1)+(5*6)+(4*9)+(3*4)+(2*0)+(1*9)=93
93 % 10 = 3
So 1694-09-3 is a valid CAS Registry Number.
