| | 4-Hydroxyaniline hydrochloride Usage And Synthesis |
| 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].
