Product Name:THORIN
English Name:THORIN
CAS No.:3688-92-4
Aliases:Thorone, Thorin reagent, APANS
Molecular Formula:C16H14AsN2NaO10S2
Physical Properties:Orange-red crystalline powder. Freely soluble in water, slightly soluble in ethanol, insoluble in ether and benzene. Exhibits orange-red color in neutral and alkaline solutions and red color in strongly acidic solutions. Contains an arsonic acid group and an azo chromophore, forming stable colored complexes with various metal ions. Maximum absorption wavelength approximately 490 nm.
Uses:Used as a chromogenic reagent and complexometric indicator in analytical chemistry, primarily for the colorimetric determination and EDTA complexometric titration of thorium, zirconium, hafnium, uranium and other metal ions. Also applied in the separation and detection of rare earth elements and analysis of metal ions in environmental water samples.
