o-Cresyl phosphate

Description:
o-Cresyl phosphate, also known as 2-cresyl phosphate, is an organophosphate compound characterized by its phosphate ester structure. It is typically a colorless to pale yellow liquid with a faint aromatic odor. This compound is soluble in organic solvents but has limited solubility in water. o-Cresyl phosphate is primarily used as a plasticizer and flame retardant in various industrial applications, including the production of plastics, rubber, and coatings. It exhibits moderate toxicity and can pose health risks upon exposure, necessitating appropriate safety measures during handling. The compound is also known to have potential environmental impacts, particularly in aquatic systems, due to its persistence and bioaccumulation potential. As with many organophosphates, it can inhibit acetylcholinesterase, leading to neurotoxic effects. Regulatory measures may apply to its use and disposal, reflecting concerns over its safety and environmental effects. Overall, o-Cresyl phosphate is a significant chemical in industrial applications, but its handling requires caution due to its toxicological properties.
