4197-07-3 Usage
Uses
Used in Analytical Chemistry:
CHROMOTROPE 2R is used as a pH indicator for complexometry, a technique used to determine the concentration of metal ions in a solution. Its color change properties allow for accurate measurement and analysis of metal ion concentrations.
Used in Histology and Cytology:
CHROMOTROPE 2R is employed as a stain in modified Gomori Trichrome stain, a histological staining technique used to visualize different structures within cells and tissues. It is particularly useful for staining collagen, muscle, and reticulin, providing contrast and enhancing the visibility of these structures.
Used in Cytology:
In cytology, CHROMOTROPE 2R is used as a stain to examine cellular structures and features. Its ability to bind to specific cellular components allows for the differentiation and identification of various cell types, aiding in the diagnosis of diseases and conditions.

Check Digit Verification of cas no
The CAS Registry Mumber 4197-07-3 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,1,9 and 7 respectively; the second part has 2 digits, 0 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 4197-07:
(6*4)+(5*1)+(4*9)+(3*7)+(2*0)+(1*7)=93
93 % 10 = 3
So 4197-07-3 is a valid CAS Registry Number.
