Uses
1. Used in Hydraulic Fluids:
Dibutyl phenyl phosphate is used as a component in hydraulic fluids for its ability to enhance the fluid's performance characteristics, such as viscosity, lubrication, and resistance to high temperatures.
2. Used as a Phosphorus Flame Retardant Additive:
Dibutyl phenyl phosphate is used as a phosphorus flame retardant additive in various materials to improve their fire resistance. Its incorporation into products helps to slow down the combustion process and reduce the risk of fire-related incidents.
Air & Water Reactions
Insoluble in water.
Reactivity Profile
Organophosphates, such as dibutyl phenyl phosphate, are susceptible to formation of highly toxic and flammable phosphine gas in the presence of strong reducing agents such as hydrides. Partial oxidation by oxidizing agents may result in the release of toxic phosphorus oxides.
Health Hazard
Dibutyl phenyl phosphate
(DBPP) has caused skin irritation in humans
after repeated or prolonged contact.
Fire Hazard
dibutyl phenyl phosphate is probably combustible.
Safety Profile
Moderately toxic by
ingestion. Experimental reproductive
effects. When heated to decomposition it
emits toxic fumes of POx.
Check Digit Verification of cas no
The CAS Registry Mumber 2528-36-1 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,5,2 and 8 respectively; the second part has 2 digits, 3 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 2528-36:
(6*2)+(5*5)+(4*2)+(3*8)+(2*3)+(1*6)=81
81 % 10 = 1
So 2528-36-1 is a valid CAS Registry Number.

A novel and efficient N,N′-carbonyl diimidazole-catalyzed protocol for the direct esterification of P(O)-OH compounds using phenols as efficient esterification reagents is illustrated. It is a simple way to synthesis a broad spectrum of functionalized O-aryl phosphinates, phosphonates, and phosphates from basic starting materials with moderate to excellent yields.

Diorganotellurides containing bulky aromatic substituents are found to catalyze the photooxidation of phosphite esters using aerobic oxygen as a terminal oxidant. A Hammett plot with substituted triaryl phosphites yielding p = 2.88 agrees with a nucleophilic oxygen transfer from telluroxide to phosphite.2009 American Chemical Society.
