| | LIGHT GREEN SF YELLOWISH Usage And Synthesis |
| Chemical Properties | deep purple powder, crystals or crystalline powder | | Uses | 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. | | Uses | As dye, biological stain. | | 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. | | 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. | | 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.
