Chemical Properties
dark red powder
Uses
Ponceau BS has been used in Masson′s trichrome stain for the staining of collagen. It has also been used for eosinophil staining.
Definition
ChEBI: An organic sodium salt having 2-[(2-hydroxynaphthalen-1-yl)diazenyl]-5-[(4-sulfonatophenyl)diazenyl]benzene-1-sulfonate as the counterion. Used as a plasma stain in Masson's trichrome.
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.
Properties and Applications
yellow light red. Soluble in water for orange red, slightly soluble in ethanol and soluble fiber element, insoluble in other organic solvents. In the dark for the strong sulfuric acid, diluted for orange red, then have a brown precipitation. In nitric acid solution for blue, then into amber color. In water solution to join strong hydrochloric acid have red precipitate; Add thick sodium hydroxide solution have yellow brown precipitation.

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.
