China and the United States are the leading exporters of Diphenylphosphoryl azide (CAS 26386-88-9), accounting for the majority of global shipments, while Germany, Japan, and South Korea represent the largest importers. These importing nations consistently absorb over 60% of total reported exports, reflecting strong demand from pharmaceutical and fine chemical manufacturing sectors. Trade volumes have remained relatively stable since 2022, with modest year-on-year fluctuations aligned with shifts in Diphenylphosphoryl azide prices and regional regulatory approvals for intermediate use.
Diphenylphosphoryl azide (DPPA) is a colorless to pale yellow liquid at room temperature, with moderate volatility and a faint, characteristic odor. It is an organophosphorus compound classified as a phosphoryl azide and is widely employed as a versatile reagent and synthetic intermediate in organic chemistry. Its primary industrial use is in the Curtius rearrangement and related transformations to generate isocyanates, carbamates, and amines—key steps in the synthesis of active pharmaceutical ingredients (APIs) and fine chemicals. DPPA is predominantly applied in pharmaceutical manufacturing and agrochemical development, where controlled nitrogen insertion and functional group interconversion are required.
