Understanding the intrinsic chemical properties of a compound is fundamental to unlocking its full industrial potential. 1-Naphthol, identified by its CAS number 90-15-3, is a prime example of a chemical intermediate whose specific characteristics dictate its widespread utility across diverse sectors. From its physical appearance to its reactivity, these properties make it invaluable as a 1-Naphthol chemical reagent and precursor.

Physically, 1-Naphthol presents as a white to off-white powder, a form that is convenient for handling, storage, and integration into various chemical processes. Its assay of ≥99.0% signifies a high degree of purity, which is critical for preventing unwanted side reactions and ensuring predictable outcomes in synthesis. Key physical parameters such as its melting point (94-96 °C) and boiling point (278-280 °C) are vital data points for chemical engineers designing reaction conditions and separation processes.

Chemically, the presence of a hydroxyl group on the naphthalene ring system imbues 1-Naphthol with characteristic phenolic reactivity. This hydroxyl group can undergo various transformations, including etherification, esterification, and nucleophilic substitution reactions. Crucially, it participates in electrophilic aromatic substitution reactions on the naphthalene ring, particularly at the 4-position, a property exploited in the synthesis of diazo dyes and other functionalized molecules. Its potential for tautomerism also influences its reaction pathways, as seen in reactions like the Bucherer reaction.

The application of 1-Naphthol extends to analytical chemistry, where it serves as a valuable 1-Naphthol chemical reagent. Its ability to form colored compounds with specific metals and biomolecules, such as in the colorimetric determination of titanium or the detection of tyrosine and proteins, highlights its utility in quantitative analysis and biochemical assays. This makes it indispensable in research laboratories and quality control settings.

For any industrial application, adherence to precise chemical specifications is non-negotiable. Manufacturers must ensure that the 1-Naphthol they procure consistently meets these standards. This is where reliable suppliers like NINGBO INNO PHARMCHEM CO.,LTD. play a critical role. By providing 1-Naphthol with guaranteed purity and well-defined properties, they empower industries to achieve optimal results, whether in the synthesis of dyes, pesticides, pharmaceuticals, or in precise analytical measurements. Understanding and leveraging these chemical properties is key to maximizing the value derived from this versatile intermediate.
