For professionals involved in chemical procurement and formulation, a thorough understanding of a compound's properties, applications, and safety profile is fundamental. Isooctyl Alcohol (CAS 26952-21-6), a branched eight-carbon alcohol, possesses a unique set of characteristics that make it valuable across numerous industrial applications, from plasticizers to solvents and beyond. Understanding these aspects is key for safe handling, effective use, and optimal sourcing.

Chemically, Isooctyl Alcohol is a primary alcohol with the molecular formula C8H18O and a molecular weight of approximately 130.23 g/mol. Its structure, typically a mixture of isomers with 2-Ethylhexanol being the most common industrial form, features a branched hydrocarbon chain attached to a hydroxyl group. This branching significantly influences its physical properties, notably its low freezing point and reduced tendency to crystallize compared to straight-chain octanols.

Physically, Isooctyl Alcohol presents as a colorless, oily liquid. It exhibits a characteristic mild, somewhat floral odor. While it has limited solubility in water (around 720 times its volume), it is miscible with most common organic solvents, which is a critical attribute for its use as a solvent in various industrial formulations. Its density is approximately 0.833 g/mL at 20°C, and its boiling point is around 170-186°C, depending on the isomer mixture. The flash point is typically above 70°C, classifying it as a combustible liquid rather than a flammable one, which aids in safer handling.

From a safety perspective, Isooctyl Alcohol is generally considered to have low acute toxicity. However, like many organic solvents, it can cause irritation upon contact with skin and eyes. Prolonged or repeated skin exposure may lead to defatting and dermatitis. Inhalation of high concentrations of vapor can cause respiratory tract irritation, dizziness, and headaches. Therefore, adequate ventilation and the use of appropriate personal protective equipment (PPE), such as gloves, safety glasses, and respiratory protection when working with large quantities or in poorly ventilated areas, are essential.

Industrial production of Isooctyl Alcohol primarily involves the oxo process followed by hydrogenation of hexanal derivatives, ensuring large-scale availability. When sourcing Isooctyl Alcohol, it is advisable to work with reputable suppliers who provide comprehensive Material Safety Data Sheets (MSDS) or Safety Data Sheets (SDS) detailing handling procedures, first aid measures, fire-fighting instructions, and disposal considerations. Adhering to these guidelines ensures safe operation and compliance with regulatory standards.

By understanding the chemical nature, physical properties, and safety requirements of Isooctyl Alcohol, industrial users can effectively integrate this versatile chemical into their processes while prioritizing safety and operational efficiency. The availability from reliable manufacturers in China offers a strong option for sourcing this important industrial ingredient.
