In the dynamic world of chemical synthesis and manufacturing, the consistent availability of high-purity intermediates is non-negotiable. 1-Naphthol, identified by its CAS number 90-15-3, is a quintessential example of such a compound. This aromatic organic chemical, a derivative of naphthalene featuring a hydroxyl group on the first carbon, serves as a vital building block across multiple critical industries, including dyes, pharmaceuticals, and agrochemicals. For professionals seeking reliable chemical partners, understanding the sourcing of 1-Naphthol is key.

The Essential Profile of 1-Naphthol

1-Naphthol, also commonly referred to as α-naphthol, is a crystalline solid recognized for its appearance as white to light yellow flakes. Its chemical formula is C10H8O, with a molecular weight of 144.17 g/mol. The hydroxyl group attached to the naphthalene ring confers phenolic properties, enabling it to participate in a variety of organic reactions, particularly electrophilic substitution. Its solubility characteristics—readily dissolving in organic solvents like ethanol and ether, but only slightly in water—are crucial for its integration into various manufacturing processes.

Key Industrial Sectors Relying on 1-Naphthol:

  • Dye Industry: 1-Naphthol is a foundational intermediate for the production of numerous azo dyes. These dyes are indispensable for imparting vibrant and durable colors to textiles, leather goods, and paper products. The coupling reactions that 1-Naphthol facilitates are central to creating a vast spectrum of colors. When you buy 1-Naphthol, you are securing a critical precursor for the global color industry.
  • Pharmaceutical Manufacturing: As a key intermediate, 1-Naphthol is instrumental in the synthesis of a wide range of pharmaceuticals, including active pharmaceutical ingredients (APIs). Its derivatives are explored for their therapeutic effects, making high-purity 1-Naphthol an essential raw material for drug development and production.
  • Agrochemical Production: In the agricultural sector, 1-Naphthol is used in the synthesis of herbicides and plant growth regulators, which are vital for crop protection and increasing agricultural yields.
  • Fragrance and Specialty Chemicals: The compound also finds application in the creation of synthetic fragrances and serves as a useful reagent in analytical chemistry.
