2391-30-2 Usage
Uses
Brilliant sulfaflavine has been used as fluorescent tracers to study the application rate of foliar fungicides when applied to soybeans for the control of rust.
Definition
ChEBI: An organic sodium salt having 6-amino-2-(4-methylphenyl)-1,3-dioxo-2,3-dihydro-1H-benzo[de]isoquinoline-5-sulfonate as the counterion. It is used as the displacement dye in the yellowsolve I method for fibrin.
Preparation
4-Amino-3-sulfo-1,8-naphthalic anhydride?with p-Methylaniline condensation.
Properties and Applications
colourful green light yellow. For yellow is soluble in water, soluble in ethanol for yellow. The strong sulfuric acid for yellow, diluted still yellow in color. The dye solution to join sodium hydroxide color becomes shallow. Used for silk, cotton and polyamide, vinegar fiber dyeing, can be in wool and silk fabric printing directly. Also used in leather, paper dyeing and used for the production of fluorescent pigments.

Check Digit Verification of cas no
The CAS Registry Mumber 2391-30-2 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,3,9 and 1 respectively; the second part has 2 digits, 3 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 2391-30:
(6*2)+(5*3)+(4*9)+(3*1)+(2*3)+(1*0)=72
72 % 10 = 2
So 2391-30-2 is a valid CAS Registry Number.
