1326-12-1 Usage
Uses
Thioflavine S is a reagent also known as Direct Yellow 7; potentially useful as an amyloid plaque stain. Dyes and metabolites.Preparation
(a) primrose spirit alkali (C.I.Direct Yellow 59, C.I. 49000) methylation, then will be preparing sulphonated product (GP 1251738); (b) primrose spirit alkali stlfonation, then will product methylation (GP 53333).Properties and Applications
green light yellow. For golden is soluble in water, but soluble in ethanol as a green fluorescent yellow. The strong sulfuric acid in nearly colorless, with blue fluorescence, after diluted orange yellow precipitation. Used for cellulose fiber, wool, silk dyeing, silk printing, also can be used for leather color. Exhaust dyeing, good levelness.

3Check Digit Verification of cas no
The CAS Registry Mumber 1326-12-1 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,3,2 and 6 respectively; the second part has 2 digits, 1 and 2 respectively.Calculate Digit Verification of CAS Registry Number 1326-12:
(6*1)+(5*3)+(4*2)+(3*6)+(2*1)+(1*2)=51
51 % 10 = 1
So 1326-12-1 is a valid CAS Registry Number.
