Applications
InP is used in high-power and high-frequency electronics because of its superior electron velocity. It also has a direct bandgap, making it useful for optoelectronics devices like laser diodes. It is also used as a substrate for epitaxial indium gallium arsenide based opto-electronic devices.

Solubility
Insoluble in water.

Notes
Store in a cool, dry conditions in a well sealed container. Incompatible with oxidizing agent.
