81-37-8 Usage
Description
FLUOROL YELLOW 088 is a polyaromatic organic dye that is used for staining plant tissue and coloring hydrocarbon solvents, grease, and paraffin wax.
Uses
Used in Plant Tissue Staining:
FLUOROL YELLOW 088 is used as a staining agent for plant tissue to provide a clear and distinct visualization of the tissue structure.
Used in Hydrocarbon Solvent Coloring:
FLUOROL YELLOW 088 is used as a colorant for hydrocarbon solvents to provide a distinct color and improve product identification.
Used in Grease and Paraffin Wax Coloring:
FLUOROL YELLOW 088 is used as a colorant for grease and paraffin wax to provide a consistent color and enhance product appearance.
Properties:
FLUOROL YELLOW 088 has a dark olive green color in mineral oil. It is insoluble in water and has stable light fastness and heat resistance. It is also stable in the presence of sodium carbonate (5%) and hydrochloric acid (5%).
Preparation
p-Cresol (2 Moore) and Phthalic anhydride (1 Moore) condensation get 2 ‘, 7 ‘- dimethyl – fluoran in 24% sulfuric acid?central change, its product with zinc and ammonia in the pressure reduction get dye, and then in 250 ~ 280 ℃ / 1-2 mmHG sublimation, refined.

Check Digit Verification of cas no
The CAS Registry Mumber 81-37-8 includes 5 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 2 digits, 8 and 1 respectively; the second part has 2 digits, 3 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 81-37:
(4*8)+(3*1)+(2*3)+(1*7)=48
48 % 10 = 8
So 81-37-8 is a valid CAS Registry Number.
