ABOUT THE PRODUCT
Product Description
Product Description-Phosphine CAS#7803-51-2
Phosphine (CAS 7803-51-2, formula PH3) is a highly toxic, flammable and explosive gas. It acts as a doping agent for semiconductor manufacturing and is also employed as an agricultural pesticide.
Given its severe hazards, phosphine demands rigorous handling and safety protocols. Even exposure to low concentrations can cause grave health damage and may prove fatal.
Product Applications-Phosphine CAS#7803-51-2
1. Semiconductor Manufacturing
It serves as an n-type silicon doping gas, delivering precise doping control with uniformity deviation ≤0.1%. It is also adopted in MOCVD processes for manufacturing GaN-based LEDs.
2. Grain Fumigation
As a grain fumigant, it achieves 99.9% pest mortality at 2 g/m³ per OECD Guideline 633. It is a low-residue substitute for methyl bromide in pest control.
3. Chemical Synthesis
It functions as a catalyst for asymmetric hydrogenation reactions, such as the preparation of chiral pharmaceutical intermediates.
