Its vivid color changes and ease of use make it an ideal choice for teaching students about the properties of metal ions and the importance of analytical chemistry in various fields.
Purification Methods
It is generally contaminated with starting material (cresol red) and semi-xylenol orange. Purify it by ion-exchange chromatography using DEAE-cellulose, eluting with 0.1M NaCl solution, which will give the sodium salt [3618-43-7].Cresol Red, semi-xylenol orange and iminodiacetic acid bands elute first. This procedure will give the sodium salt of the dye.To obtain the free acid, dissolve the salt in H2O and acidify it with AcOH. Filter it off, wash it with H2O and dry it first in air and then in a vacuum desiccator over P2O5 in the dark [Sato et al. Anal Chim Acta 94 317 1977].

Check Digit Verification of cas no
The CAS Registry Mumber 1611-35-4 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,6,1 and 1 respectively; the second part has 2 digits, 3 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 1611-35:
(6*1)+(5*6)+(4*1)+(3*1)+(2*3)+(1*5)=54
54 % 10 = 4
So 1611-35-4 is a valid CAS Registry Number.
