4-(Benzyloxy)benzoic acid(CAS: 1486-51-7)

4-(Benzyloxy)benzoic acid is a white crystalline solid with a molecular weight of approximately 248.23 g/mol. It has a pKa of around 4.2. This compound is only slightly soluble in water but soluble in most organic solvents. It is moderately reactive towards bases and can undergo esterification reactions.

4-(Benzyloxy)benzoic acid is typically synthesized by reacting benzoic acid with benzylic alcohol in the presence of a dehydrating agent like phosphorus pentoxide (P2O5) or thionyl chloride (SOCl2). The reaction is usually carried out under reflux conditions to ensure complete conversion and high yield.

4-(Benzyloxy)benzoic acid is widely used in the pharmaceutical industry for the synthesis of intermediate compounds, as well as in the production of some active pharmaceutical ingredients. It also finds applications in the polymer industry for modifying the properties of plastics and in the chemical sensors industry for detecting specific analytes.

When handling 4-(Benzyloxy)benzoic acid, it is important to wear appropriate personal protective equipment (PPE) such as gloves, goggles, and a lab coat. Work should be conducted in a well-ventilated area or a fume hood to minimize exposure. Spills should be cleaned up carefully using appropriate absorbent materials and following standard safety protocols. Always consult the Safety Data Sheet (SDS) for detailed handling instructions.
