CAS 53936-56-4 — Tetrahydropyranyloxyphenol

Tetrahydropyranyloxyphenol (THPP) is a protected phenol derivative widely used in organic synthesis as a stable intermediate for phenolic compounds, particularly in pharmaceuticals, agrochemicals, and fine chemicals. It acts as a blocking agent to prevent oxidation or polymerization during multi-step reactions. This high-purity reagent is a clear to pale yellow liquid with a mild odor, soluble in organic solvents but insoluble in water. It has a molecular weight of 180.24 g/mol and a boiling point of around 240°C (decomposition). Molekula supplies Tetrahydropyranyloxyphenol from research to bulk quantities with full documentation and ISO 9001:2015 traceability.
