In the intricate world of chemical manufacturing, certain compounds stand out for their versatility and indispensability. 1-Naphthol, with its CAS number 90-15-3, is one such chemical. This aromatic organic compound, a derivative of naphthalene featuring a hydroxyl group, is a cornerstone for industries ranging from textiles to pharmaceuticals, and even agrochemicals. Understanding its properties and reliable sourcing channels is key for any procurement professional or research scientist.

The Chemical Profile of 1-Naphthol

1-Naphthol, also known as α-naphthol, presents as a white to off-white crystalline solid. Its chemical formula is C10H8O, and its molecular weight is approximately 144.17 g/mol. The presence of the hydroxyl group attached directly to the naphthalene ring system imbues it with phenolic characteristics, making it slightly acidic and highly reactive in various organic transformations.

Its solubility profile is notable: while sparingly soluble in water, it readily dissolves in common organic solvents such as ethanol, ether, and chloroform. This characteristic is vital for its use in various chemical processes and formulations.

Key Industrial Applications of 1-Naphthol

The significance of 1-Naphthol lies in its broad spectrum of applications:

  • Dye Synthesis: Historically and currently, 1-Naphthol is a critical intermediate for producing a vast array of azo dyes. These dyes are sought after for their vibrant colors and fastness properties, essential for the textile, leather, and paper industries. As a coupling component, it reacts with diazonium salts to form these colorful compounds. When you buy 1-Naphthol for dye production, you are investing in the very foundation of color.
  • Pharmaceutical Manufacturing: The compound serves as a crucial building block in the synthesis of numerous pharmaceuticals. It is a precursor for certain APIs, and its derivatives are explored for their therapeutic potential, including in the development of cardiovascular drugs and other medicinal agents. Sourcing pharmaceutical-grade 1-Naphthol is paramount for this sector.
  • Agrochemicals: In the agricultural sector, 1-Naphthol acts as an intermediate in the production of pesticides and herbicides. Its chemical structure lends itself to creating compounds that protect crops from pests and weeds, thereby improving agricultural yields.
  • Fragrance Industry: The aromatic nature of 1-Naphthol also finds application in the creation of synthetic fragrances and perfumes.
  • Analytical Reagent: In laboratory settings, it's recognized for its use in chemical tests, such as the Molisch test to detect carbohydrates, underscoring its utility in analytical chemistry.
