1-Naphthol, a compound with the chemical name 1-hydroxynaphthalene and CAS number 90-15-3, is far more than just a chemical substance; it's a critical component that enables innovation across multiple industries. Available typically as off-white to light grey flakes, this organic intermediate's unique chemical properties make it indispensable in a surprising range of applications, from the vibrant colors of hair dyes to the complex synthesis pathways of modern pharmaceuticals.

One of the most recognized applications for 1-Naphthol is its role as an intermediate in the production of hair dyes. In this sector, it acts as a coupling agent. When combined with diazonium salts, it forms azo dyes that are responsible for imparting a wide spectrum of stable and appealing colors to hair. The quality and purity of the 1-Naphthol used directly influence the brilliance, longevity, and safety of the final hair dye product. Therefore, sourcing high-purity 1-Naphthol from a trusted manufacturer is essential for cosmetic formulators.

Beyond personal care, 1-Naphthol is a highly valued intermediate in the pharmaceutical industry. Its structure serves as a crucial building block for synthesizing various APIs. Medicinal chemists utilize its reactive hydroxyl group and naphthalene ring system to construct complex molecular architectures that form the basis of numerous therapeutic agents. When you need to buy 1-Naphthol for pharmaceutical synthesis, ensuring it meets stringent purity standards (often ≥99.0%) is paramount to avoid unwanted side reactions and ensure the safety and efficacy of the final drug.

The versatility of 1-Naphthol extends to broader organic synthesis. It is employed in the creation of other fine chemicals, agrochemicals, and pigments. Its ability to undergo electrophilic aromatic substitution and coupling reactions makes it a foundational reagent for chemists looking to develop novel compounds. Whether you are a procurement manager seeking reliable raw materials or a research scientist exploring new molecular pathways, understanding the applications of 1-Naphthol can guide your sourcing decisions.

For businesses looking to secure a consistent and high-quality supply of 1-Naphthol, identifying a reputable manufacturer and supplier is key. Look for providers who can offer detailed product specifications, competitive pricing, and a commitment to quality assurance, ensuring that you can confidently integrate this essential intermediate into your production processes.
