5141-20-8 Usage
Chemical Properties
deep purple powder, crystals or crystalline powder
Uses
Different sources of media describe the Uses of 5141-20-8 differently. You can refer to the following data:
1. As dye, biological stain.
2. Light Green SF Yellowish is an acid dye, and a water pollutant. Oxidation of light green SF yellowish results in colour loss, making it an excellent indicator in the detection of trace cerium. Dyes and metabolites.
Preparation
Benzaldehyde (1 Moore) and N-benzyl-N-ethylbenzenamine (2 Moore) condensation, and then three stlfonation, and will product oxidation and will last them into sodium salt.
Definition
ChEBI: An organic sodium salt having 3-[(ethyl{4-[(4-{ethyl[(3-sulfonatophenyl)methyl]amino}phenyl)(4-sulfonatophenyl)methylidene]cyclohexa-2,5-dien-1-ylidene}azaniumyl)methyl]benzene-1-sulfonate as the counterion. It is the standard dye in North American for sta
ning collagen and is also used extensively in plant histology.
Properties and Applications
green. SAP green powder. Easy to dissolve in water (a blue light green), and very difficult to soluble in alcohol. Strong sulfuric acid in orange, yellow is diluted. Dye with sodium hydroxide solution nearly colorless, has the purple precipitation.

Check Digit Verification of cas no
The CAS Registry Mumber 5141-20-8 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,1,4 and 1 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 5141-20:
(6*5)+(5*1)+(4*4)+(3*1)+(2*2)+(1*0)=58
58 % 10 = 8
So 5141-20-8 is a valid CAS Registry Number.
