Fragrance Industry
Because of its odour reminiscent of scented geranium, as well as its stability and low price, diphenyl ether is used in large quantities in soaps, detergents & incense sticks. It is also used in many perfumes and has other perfumery applications.

Heat Transfer Medium
DPO when blended with Biphenyl produces Thermic Fluid, which is widely used as high temperature heat transfer media. Such a mixture is well-suited for heat transfer applications because of the relatively large temperature range of its liquid state.

Blowing Agent
DPO is used in the manufacturing of blowing agents for rubber.

Fire Retardant
DPO on bromination gives Deca Bromo Diphenyl oxide, which is widely used in the plastics industry as a fire retardant.

Lubricants & Industrial Surfactants
Used in the manufacturing of high – temperature lubricants & industrial surfactants. In specialty surfactants which finds application in textiles, mining, petroleums, agriculture etc.

Flavour Industry
Due to its rosy, floral, geranium-like flavour it is used as a flavour for vegetable, yellow fruit, tropical fruit and other sweet flavours ingredients.

Solvent for drugs
DPO can be used as a high boiling reaction solvent in the manufacturing of drugs like Chloroquine Phosphate (anti- malarial drug), Norfloxacin, Perfloxacin, Ciprofloxacin (broad spectrum antibiotics) etc.

Heat – transfer medium resins for laminated electrical insulation, chemical intermediate for such reactions as halogenations, Acylation, Alkylation etc.
