Used primarily in Flame - Fire Retardants, Industrial / Manufacturing, Plasticizers & Polymer, Solvents & Cleaning, and Tech, Energy & Fuel applications, Tri-o-tolyl phosphate is specifically used in chemical intermediate, extractant, flame retardant, lead scavenger, lubricant, plasticizer, solvent, and water-proofing agent.
Tri-o-cresyl phosphate is an organophosphorus compound and is one of the three major isomers of tricresyl phosphates, the other two being tri-p-cresyl phosphate (CAS #78-32-0) and tri-m-cresyl phosphate (CAS #563-40-2). These chemicals are mainly used as additives in lubricating oils and as plasticizers and flame retardants (NJ Health 2011). Tri-o-cresyl phosphate is prepared from cresol and phosphorus oxychloride, phosphoric acid, or phosphorus pentachloride. The commercial product is generally a mixture of isomers (CAS #1330-78-5) (HSDB 2011). However, tri-o-cresyl phosphate is largely removed from commercial tricresyl phosphate, primarily due to its neurotoxicity (van der Veen and de Boer 2012).
