Product Description of 4-(2-Tetrahydropyranyloxy)phenylboronic Acid CAS#182281-01-2
4-(2-Tetrahydropyranyloxy)phenylboronic acid is a functional organoboron intermediate, which is the tetrahydropyranyl-protected form of 4-hydroxyphenylboronic acid. At room temperature, it generally appears as a white to pale-yellow solid. The tetrahydropyranyl group effectively shields the phenolic hydroxyl group, preventing side-reactions during synthetic operations.
This boronic acid monomer exhibits good reactivity in common palladium-catalyzed cross-coupling transformations. It has limited solubility in water and dissolves readily in many anhydrous organic solvents.

Product Application of 4-(2-Tetrahydropyranyloxy)phenylboronic Acid CAS#182281-01-2
This boronic-acid reagent is mainly applied for Suzuki-Miyaura cross-coupling reactions and acts as a vital synthetic intermediate in drug-development workflows.
It can be adopted to construct anti-cancer dichloroacetamide analogues and other bio-active molecular frameworks. The removable tetrahydropyranyl protecting group masks the hydroxyl site throughout multi-step synthetic routes, suppressing unwanted side reactions and improving overall reaction selectivity and product yield. Thanks to this protective-group structure, the compound is suitable for complex organic synthesis, especially for the manufacture of fine-chemical and pharmaceutical candidates.
