n-Hexane AR (Analytical Reagent grade) is a high-purity organic solvent widely utilized in laboratory and industrial settings. Its chemical formula is C6H14, and it possesses the CAS number 110-54-3. This colorless, volatile liquid belongs to the alkane family and is characterized by its distinct gasoline-like odor. As an analytical reagent, n-Hexane AR meets stringent purity standards, typically exceeding 99% with minimal impurities such as benzene, making it ideal for sensitive analytical procedures where background interference must be eliminated.
The primary application of n-Hexane AR lies in chromatography, particularly as a mobile phase component in gas chromatography (GC) and liquid chromatography (LC). Its non-polar nature allows for the effective separation of hydrocarbons and other non-polar compounds. Additionally, it serves as a crucial extraction solvent in food analysis, specifically for determining fat content in grains, oils, and dairy products according to standardized methods like AOAC and ISO protocols. In pharmaceutical research, it is employed for the purification of active ingredients and the preparation of extracts.
Beyond the laboratory, n-Hexane finds extensive use in the manufacturing of adhesives, rubber, and printing inks due to its excellent solvency properties. However, its usage requires strict safety precautions. It is highly flammable and poses significant health risks upon prolonged exposure, including neurotoxicity that can affect the peripheral nervous system. Therefore, handling must occur in well-ventilated areas with appropriate personal protective equipment. The "AR" designation ensures that the product is suitable for precise quantitative and qualitative analysis, guaranteeing reproducible results in scientific investigations. While cost-effective and efficient, users must adhere to local environmental regulations regarding disposal to prevent soil and water contamination. Overall, n-Hexane AR remains an indispensable reagent in modern chemistry, balancing utility with the need for rigorous safety management.
