For professionals involved in chemical synthesis, research and development, and manufacturing, a thorough understanding of key chemical properties and safety considerations for essential compounds is vital. This article provides comprehensive information on 3-Aminophenol (CAS 591-27-5), detailing its physical and chemical characteristics, and highlighting crucial safety guidelines for handling and storage. As a leading manufacturer in China, we aim to equip our partners with the knowledge they need for effective and safe utilization of this compound.

3-Aminophenol, also known as m-aminophenol or 3-hydroxyaniline, is an organic compound with the molecular formula C6H7NO. It typically presents as white to light gray or pinkish crystals. Its molecular weight is approximately 109.13 g/mol. Key physical properties include a melting point range of 120-124 °C and a boiling point of 164 °C at 11 mmHg. Its solubility in water is notable, being soluble at 35 g/L at 20 °C, and it is also soluble in ether and alcohol, though less so in benzene.

Chemically, 3-Aminophenol exhibits dual reactivity due to the presence of both an amine group and a hydroxyl group. The pKa values are approximately 4.37 for the amino group and 9.82 for the phenolic hydroxyl group, indicating its behavior in acidic and basic environments. This bifunctionality makes it a valuable intermediate for various chemical reactions, including etherification, esterification, and diazotization, leading to a broad spectrum of derivative compounds.

Safety is paramount when working with any chemical. 3-Aminophenol is classified as harmful if swallowed or inhaled and toxic to aquatic life with long-lasting effects (GHS hazard statements H302, H332, H411). Appropriate personal protective equipment (PPE) is essential, including respiratory protection (dust masks like N95), eye protection (eyeshields), and gloves. When handling, it is crucial to avoid breathing dust/fume/gas/mist/vapors/spray and to avoid release into the environment. Always ensure adequate ventilation and follow safe handling procedures. Storage should be in a cool, well-ventilated place, with containers kept tightly closed.
