Product Name:Acid Red 94
English Name:Tetrachlorotetraiodofluorescein disodium salt
CAS No.:632-69-9
Aliases:Tetraiodotetrachlorofluorescein, Tetraiodotetrachlorofluorescein disodium salt
Molecular Formula:C20H2Cl4I4Na2O5
Physical Properties:Reddish-brown powder, odorless. Easily soluble in water, sparingly soluble in hard water; soluble in glycerol and ethylene glycol; insoluble in oils and ether. A 1% aqueous solution has a pH of 6.5–10 and appears bluish red. It has good heat resistance, oxidation resistance, reduction resistance, alkali resistance, and salt resistance; poor light resistance and acid resistance; precipitation occurs upon contact with acid.
Uses:Primarily used as a food red colorant for coloring cherries, fish cakes, fish-stuffed seaweed rolls, sausages, pastries, and fish floss, with a typical dosage of 5–100 mg/kg. It is also used for biological tissue staining.
Technical Specifications:
Molecular formula: C20H2Cl4I4Na2O5, molecular weight approximately 1017.62
Appearance: reddish-brown powder, odorless
Solubility: easily soluble in water, sparingly soluble in hard water; soluble in glycerol and ethylene glycol; insoluble in oils and ether
pH of 1% aqueous solution: 6.5–10, appearing bluish red
Stability: good heat resistance, oxidation resistance, reduction resistance, alkali resistance, and salt resistance; poor light resistance and acid resistance
