Overview
Allylphenol is an organic compound featuring a phenol group substituted with an allyl group. It serves as a versatile intermediate in chemical synthesis, particularly in the production of resins, pharmaceuticals, and fragrances. Its reactive allyl group makes it valuable for further functionalization in industrial applications. The compound is typically supplied as a colorless to pale yellow liquid with a characteristic phenolic odor. Due to its reactivity, it is often handled under controlled conditions to prevent unwanted polymerization or degradation.
Physical and Chemical Properties
Allylphenol has a molecular weight of 134.18 g/mol and a density of approximately 1.02 g/cm³. It boils at 220-222 °C and is soluble in common organic solvents like ethanol and ether, though its solubility in water is limited. The presence of both phenolic and allylic functionalities imparts unique reactivity, enabling its use in diverse chemical transformations. Key chemical properties include its ability to undergo electrophilic substitution reactions at the phenol ring and addition reactions at the allyl group. These characteristics make it a valuable precursor in synthetic chemistry.
Main Applications
Allylphenol is primarily used as an intermediate in the synthesis of specialty chemicals. In the resin industry, it contributes to the production of allyl-modified phenolic resins, which exhibit enhanced thermal stability and mechanical properties. These resins find applications in coatings, adhesives, and composite materials. In pharmaceuticals, allylphenol derivatives are explored for their bioactive properties. The compound also serves as a building block for fragrances and agrochemicals, where its structural features are leveraged to create specific olfactory or pesticidal effects.
Safety and Storage
Allylphenol is classified as an irritant, posing risks to skin, eyes, and respiratory systems upon exposure. Proper personal protective equipment (PPE), including gloves and goggles, is essential during handling. Adequate ventilation is recommended to minimize inhalation hazards. Storage should occur in a cool, dry environment, away from heat sources and open flames. Containers must be tightly sealed to prevent oxidation or moisture absorption. Incompatible materials include strong oxidizers, which may lead to hazardous reactions.
B2B Procurement Guide
When procuring allylphenol, buyers should prioritize suppliers who provide detailed technical data sheets (TDS) and certificates of analysis (CoA). Key specifications to verify include purity (typically 98% or higher), CAS number (1745-81-9), and absence of contaminants. Bulk purchases often yield cost savings, but storage capacity and shelf-life considerations must be evaluated. Establish clear agreements on packaging (e.g., drums or intermediate bulk containers) and logistics to ensure safe transportation and minimal downtime.
