For professionals in chemical research, development, and procurement, a deep understanding of a chemical's properties is fundamental to successful application and safe handling. 4-Tert-Octylphenol (PTOP), identified by CAS number 140-66-9, is an important industrial chemical intermediate whose physical and chemical characteristics dictate its utility and the precautions required during its use and storage.

Key Physical Characteristics of PTOP
When procuring 4-Tert-Octylphenol, its appearance is a primary indicator of quality. It is typically supplied as a white flake solid. This physical form is stable under normal conditions and facilitates easier handling compared to liquids or fine powders. The melting point of PTOP is generally reported in the range of 79-82°C. This relatively high melting point confirms its solid state at room temperature and is an important parameter for processes involving heating or dissolution.

Chemical Properties and Solubility
Chemically, 4-Tert-Octylphenol is an alkylphenol, characterized by a phenol ring substituted with a tertiary octyl group. Its molecular formula is C14H22O, and its molecular weight is approximately 206.32 g/mol. Understanding its solubility is critical for formulation work. PTOP exhibits slight solubility in water, with a value of 0.007 g/L at 20°C. However, it is readily soluble in many organic solvents, such as alcohols, ethers, and aromatic hydrocarbons, which is key to its use in resin synthesis and as an intermediate for soluble surfactants.

Reactivity and Stability
4-Tert-Octylphenol is considered stable under recommended storage conditions. It is important to note its incompatibilities: it should be kept away from strong oxidizing agents and strong bases, as these can lead to undesirable reactions. Proper storage in a cool, dry, well-ventilated area, away from direct sunlight and heat sources, is crucial to maintain its purity and stability. For those looking to buy 4-tert-octylphenol, these properties guide safe handling and storage protocols.

Ensuring Quality Through Specifications
When sourcing PTOP, especially from an international 4-tert-octylphenol supplier or manufacturer, always verify the product specifications. A typical high-quality industrial grade will boast a purity of u226598.5%. These details are vital for formulators and R&D scientists to ensure predictable reaction outcomes and the desired performance in their final products, whether they are surfactants, resins, or other specialized chemicals. Obtaining competitive 4-tert-octylphenol prices from reliable sources often involves looking at these precise specifications.

Conclusion
The physical and chemical profile of 4-Tert-Octylphenol—its white flake solid appearance, specific melting point, limited water solubility, and good organic solvent solubility—makes it a versatile and manageable intermediate. By understanding these properties and prioritizing suppliers who offer verifiable specifications, professionals can confidently source and utilize PTOP for their manufacturing needs, ensuring both product quality and operational safety.
