4-Hydroxyaniline hydrochloride Chemical Properties,Usage,Production
Chemical Properties
Off white powder
Uses
4-Aminophenol may be used as a pharmaceutical reference standard for the determination of the analyte in pharmaceutical formulations using surface enhanced Raman scattering method.
General Description
Pharmaceutical secondary standards for application in quality control, provide pharma laboratories and manufacturers with a convenient and cost-effective alternative to the preparation of in-house working standards. 4-Aminophenol hydrochloride can be used to study cell biology, bioactive small molecules, chemical synthesis, organic building blocks, oxygen compounds and phenols.
Safety Profile
Moderately toxic byintraperitoneal route. Mutation data reported. Whenheated to decomposition it emits very toxic fumes of HCland NOx.
Purification Methods
Purify the salt by treating an aqueous solution with saturated Na2S2O3, filtering under N2, then recrystallising it from 50% EtOH twice and once from absolute EtOH [Livingston & Ke J Am Chem Soc 72 909 1950]. [Beilstein 13 III 993.]
