Dibutyl phosphate

Description:
Dibutyl phosphate (DBP) is an organic compound with the chemical formula C8H17O4P. It is classified as an ester, specifically a phosphate ester, formed from the reaction of phosphoric acid and butanol. DBP is a colorless to pale yellow liquid with a characteristic odor and is soluble in organic solvents while being only slightly soluble in water. It is primarily used as a plasticizer, solvent, and in various industrial applications, including as a chemical intermediate in the production of other compounds. DBP exhibits low volatility and has a relatively high boiling point, making it stable under normal conditions. However, it can be toxic to aquatic life and may pose environmental risks, leading to regulatory scrutiny. Safety data sheets indicate that it can cause skin and eye irritation upon contact. As with many phosphate esters, it is important to handle dibutyl phosphate with care, following appropriate safety guidelines to minimize exposure and environmental impact.
