In the realm of industrial chemistry, certain compounds stand out for their versatility and broad applicability. 2-Octanol, identified by CAS 4128-31-8 and often referred to as capryl alcohol or methyl hexyl carbinol, is one such indispensable chemical. As a C8 secondary alcohol, it possesses a unique combination of physical and chemical properties that make it highly sought after across numerous sectors. For R&D scientists and formulators, understanding its characteristics and sourcing reliable supply is key to successful product development.

Understanding the Chemical Profile of 2-Octanol

2-Octanol (C8H18O) is characterized by its colorless, clear liquid appearance and a molecular weight of approximately 130.23 g/mol. Its structure, with a hydroxyl group at the second carbon of an eight-carbon chain, confers amphiphilic properties, allowing it to interact with both polar and nonpolar substances. This amphiphilicity, combined with its status as a secondary alcohol, dictates its behavior in various chemical reactions and formulations.

Key physical properties include a boiling point typically between 174-181°C, a melting point around -38°C, and a density of approximately 0.819 g/mL. These attributes contribute to its utility as a high-boiling solvent, offering good miscibility with many organic solvents while exhibiting limited solubility in water (around 1.2 g/L at 25°C). Its relatively low vapor pressure and flash point of around 71°C (closed cup) contribute to safer handling and storage compared to more volatile solvents.

Industrial Applications: A Versatile Building Block

The true value of 2-Octanol is realized in its diverse industrial applications:

  • Solvents for Coatings, Inks, and Adhesives: Its high boiling point and excellent solvency for resins and oils make it an effective solvent, improving formulation viscosity, flow, and film formation. Companies looking to buy efficient solvents for their coating or ink production will find 2-Octanol a valuable option.
  • Chemical Intermediate for Plasticizers: A significant application is its esterification with phthalic anhydride to produce dioctyl phthalate (DOP), a primary plasticizer used extensively in PVC products. Sourcing this intermediate is crucial for manufacturers of flexible plastics.
  • Fragrance and Flavor Formulations: 2-Octanol is utilized in the fragrance industry to create or enhance fruity and floral notes. It serves as a key component in perfumes, cosmetics, and even certain food additives. Buyers in this sector seek consistent quality for precise scent profiles.
  • Surfactants and Emulsifiers: Through processes like ethoxylation, 2-Octanol can be converted into non-ionic surfactants, widely used in detergents, personal care products, and industrial formulations for their wetting, emulsifying, and dispersing properties.
  • Lubricant Additives and Defoamers: It finds application in the synthesis of lubricant additives, such as zinc dithiophosphates (ZDDP), and acts as a defoaming agent in various industrial processes, including pulp and paper, oil and gas, and cement manufacturing.
  • Pharmaceutical Intermediates: In specialized organic synthesis, 2-Octanol can serve as a precursor for certain pharmaceutical compounds.
