In the vast field of chemical compounds, intermediates like 1-Amino-7-naphthol (CAS: 118-46-7) are indispensable due to their versatile applications and reactive functionalities. Primarily recognized for its role in the synthesis of dyes and its utility as a pharmaceutical intermediate, this naphthalene derivative is a subject of significant interest for industry professionals. Understanding its chemical profile—including physical properties, reactivity, and key applications—is crucial for anyone looking to procure this compound. This article aims to provide a comprehensive overview and guide procurement managers and R&D scientists to reliable sources.

Understanding the Chemical Identity

1-Amino-7-naphthol, also known by synonyms such as 8-amino-2-naphthol or 1-amino-7-hydroxynaphthalene, is an organic compound with the molecular formula C10H9NO and a molecular weight of approximately 159.18 g/mol. Its structure features a naphthalene ring system with an amino (-NH2) group and a hydroxyl (-OH) group attached at specific positions. Key physical properties often include a melting point in the range of 206-210 °C and a typical appearance as a white to gray-brown powder. Its solubility is generally higher in organic solvents than in water, owing to the hydrophobic nature of the naphthalene core.

Applications: From Colorants to Pharmaceuticals

The industrial significance of 1-Amino-7-naphthol stems from its dual role: it is a vital intermediate in the synthesis of azo dyes, contributing to a spectrum of colors used in textiles, leather, and paper. Dyes like neutral brown VRL, dark brown 5R, neutral black BRL, and black BGL rely on this compound for their formation. Furthermore, its chemical structure makes it a valuable building block in the pharmaceutical industry. As a pharmaceutical intermediate, it aids in the synthesis of complex organic molecules that form the basis of various therapeutic agents. For these applications, particularly in pharmaceuticals, high purity (e.g., 99% min) is a critical requirement.

Sourcing High-Quality 1-Amino-7-naphthol

Procuring 1-Amino-7-naphthol requires careful selection of suppliers. Buyers should look for manufacturers who can guarantee high purity and consistent quality, often backed by detailed specifications and certificates of analysis. Competitive pricing is also a key consideration, especially when purchasing in bulk. Reputable manufacturers, including those in China, often provide free samples for laboratory testing, allowing R&D scientists to verify the compound's suitability for their specific synthesis needs. When searching for this chemical, terms like 'buy 1-Amino-7-naphthol' or '1-Amino-7-naphthol supplier' will lead to potential sources.
