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.] |
