Product Name:Hydroxy Naphthol Blue
English Name:Hydroxy Naphthol Blue
CAS No.:63451-35-4
Aliases:Hydroxy Naphthol Blue sodium salt, HNBS
Molecular Formula:C20H15N2NaO11S3
Physical Properties:Dark red to violet-black crystalline powder, soluble in water, slightly soluble in ethanol, insoluble in ether and most organic solvents. The aqueous solution is blue and undergoes a distinct color change upon chelation with metal ions under alkaline conditions, with good stability.
Uses:Used as a metal titration indicator for the detection of alkaline earth metal ions (e.g., calcium, magnesium) and rare earth metal ions. It is also applicable in photometric analysis for the determination of certain metal ions.
Technical Specifications:
Appearance: dark red to violet-black crystalline powder
Soluble in water, slightly soluble in ethanol, insoluble in ether and other non-polar organic solvents
Aqueous solution is blue and exhibits sharp color change upon complexation with metal ions
Used as a metal indicator in EDTA complexometric titration with a clear endpoint
