Overview
4-Octylaniline is an organic compound belonging to the class of aromatic amines, characterized by an octyl group attached to the para position of an aniline molecule. It serves as a versatile intermediate in chemical synthesis, particularly in the production of dyes, pigments, and pharmaceuticals. The compound's hydrophobic octyl chain enhances its solubility in organic solvents, making it useful in formulations requiring non-polar characteristics. In industrial settings, 4-octylaniline is valued for its role in creating specialized chemical products. Its synthesis typically involves the alkylation of aniline with octyl halides or similar reagents. The compound's reactivity allows for further functionalization, enabling its use in complex organic syntheses.
Physical and Chemical Properties
4-Octylaniline is a colorless to pale yellow liquid at room temperature, with a molecular weight of 205.34 g/mol. Its density is approximately 0.91 g/cm³, and it has a boiling point around 300°C. The compound is soluble in common organic solvents like ethanol, ether, and acetone but exhibits negligible solubility in water due to its hydrophobic octyl chain. Chemically, 4-octylaniline behaves as a typical aromatic amine, capable of participating in electrophilic substitution reactions. The para position of the octyl group influences its reactivity, often directing further substitutions to the ortho and meta positions. The compound's stability under normal conditions makes it suitable for storage and handling in industrial environments, though it requires protection from strong oxidizing agents.
Main Applications
The primary use of 4-octylaniline is as an intermediate in the synthesis of dyes and pigments, where it contributes to the formation of complex colorants. Its hydrophobic properties make it particularly useful in creating oil-soluble dyes for textiles, inks, and coatings. The compound also finds applications in pharmaceutical research, serving as a building block for active pharmaceutical ingredients (APIs) and other bioactive molecules. In addition to its industrial uses, 4-octylaniline is employed in academic and research laboratories for studying aromatic amine chemistry. Its role in specialty chemical production, such as surfactants and corrosion inhibitors, further underscores its versatility. The compound's ability to act as a ligand in coordination chemistry also opens avenues for catalytic applications.
Safety and Storage
4-Octylaniline poses several health hazards, including toxicity upon ingestion or inhalation and irritation to the skin and eyes. Proper personal protective equipment (PPE), such as gloves, goggles, and lab coats, is essential when handling the compound. Adequate ventilation or fume hoods should be used to minimize inhalation risks. Storage recommendations include keeping the compound in a cool, dry place away from direct sunlight and oxidizing agents. Containers should be tightly sealed to prevent moisture absorption and contamination. In case of spills, absorbent materials like sand or vermiculite should be used, followed by proper disposal in accordance with local regulations.
B2B Procurement Guide
When procuring 4-octylaniline, B2B buyers should prioritize suppliers with verified certifications and a track record of delivering high-purity chemicals. The compound is typically available in quantities ranging from laboratory-scale (grams) to bulk industrial quantities (kilograms or tons). Purity levels of 98% or higher are recommended for most applications to ensure consistent performance. Price ranges vary depending on purity, quantity, and supplier, with common benchmarks between $50 and $200 per kilogram. Buyers should request material safety data sheets (MSDS) and certificates of analysis (CoA) to confirm quality. Bulk purchases may qualify for discounts, and long-term supply agreements can stabilize costs. Lead times should be confirmed in advance, especially for custom or large orders.
