Description
Acid Red 66, also known as Ponceau BS, is a synthetic azo dye characterized by its red color. It is a water-soluble dye with a molecular structure that includes azo groups, which are responsible for its color. Acid Red 66 is commonly used in various applications due to its color properties and solubility.
Uses
Used in Histopathology:
Acid Red 66 is used as a staining agent in Masson's trichrome stain for the staining of collagen. It provides a distinct red color to collagen fibers, allowing for clear visualization and differentiation from other tissue components.
Used in Eosinophil Staining:
In addition to collagen staining, Acid Red 66 is also used for eosinophil staining. Eosinophils are a type of white blood cell involved in immune responses, and staining with Acid Red 66 helps in identifying and analyzing these cells in various biological samples.
Preparation
3,4′-Disulfo-4-aininoazobenzene?diazo, and Naphthalen-2-ol coupling.
Biochem/physiol Actions
Ponceau BS is used in Masson′s trichrome staining procedure, along with acid fuchsin, for the labeling of collagen and muscle red.

Check Digit Verification of cas no
The CAS Registry Mumber 4196-99-0 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 6 respectively; the second part has 2 digits, 9 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 4196-99:
(6*4)+(5*1)+(4*9)+(3*6)+(2*9)+(1*9)=110
110 % 10 = 0
So 4196-99-0 is a valid CAS Registry Number.
