Di-o-tolyl hydrogen phosphate

Di-o-tolyl hydrogen phosphate (DTP) is a chemical compound with the chemical formula C14H15O4P and a molecular weight of 276.24 g/mol. It is a colorless to pale yellow liquid that is used primarily as a flame retardant in the production of plastics, resins, and synthetic fibers.

DTP is a member of the organophosphate flame retardant (OPFR) family, which can be found in a wide range of consumer products. It is known to be persistent and has been detected in the environment, including in air, water, and soil.

Studies have suggested that DTP may have adverse effects on human health, including reproductive and developmental toxicity, as well as neurotoxicity. It has also been shown to have endocrine-disrupting properties, which can interfere with the body's hormonal balance.

Due to concerns about the potential health and environmental impacts of DTP and other OPFRs, many regulatory agencies have begun to restrict their use and promote the development of safer alternatives.
