Product Name:Dipotassium 2-aminophenol-4,6-disulfonate
English Name:Dipotassium 2-aminophenol-4,6-disulfonate
CAS No.:79817-61-1
Aliases:2-Amino-4,6-disulfophenol dipotassium salt, 5-Amino-4-hydroxybenzene-1,3-disulfonic acid dipotassium salt, Dipotassium 2-amino-4,6-disulfonatophenolate
Molecular Formula:C6H5K2NO7S2
Physical Properties:White to off-white crystalline powder, freely soluble in water, slightly soluble in ethanol, insoluble in ether and benzene. The aqueous solution is weakly alkaline. Melting point above 300°C (decomposition). It is hygroscopic and should be kept sealed and stored in a dry place.
Uses:As an aromatic sulfonated intermediate, it is widely used in the synthesis of azo dyes, reactive dyes and acid dyes. It serves as an aromatic amine sulfonating reagent in organic synthesis and is also employed in the preparation of fluorescent brighteners and pharmaceutical intermediates. Due to its good water solubility, it is additionally used as an analytical reagent for metal ion complexation colorimetry.
Technical Specifications:
Appearance: white to off-white crystalline powder
Assay (on dry basis): ≥98%
Melting point: >300°C (decomposition)
Loss on drying: ≤0.5%
pH value of 1% aqueous solution: 7.0~9.0
