Phosphorus Pentoxide for Advanced Chemical Applications

Powerful dehydration meets phosphorus chemistry.
Nagase supplies high-purity P₂O₅ for use in electronics, fine chemical synthesis, and phosphorus-based compound production.

High-Purity P₂O₅ for Industrial and Laboratory Use

Phosphorus pentoxide (P₂O₅) is a highly hygroscopic white solid used as a dehydrating agent and as a versatile intermediate in the synthesis of phosphorus-based compounds. In electronics and specialty chemical manufacturing, it is a key raw material for producing high-purity phosphoric acid, organophosphorus derivatives, and moisture-sensitive reagents. Its strong affinity for water also makes it effective for controlled drying processes and atmospheric conditioning in laboratory and industrial settings.

As a reliable global supplier, NAGASE provides phosphorus pentoxide in high-purity grades with flexible packaging options and secure international logistics support.
