tricresyl
Tricresyl, more commonly referred to as tricresyl phosphate (TCP), is a family of organophosphate esters derived from cresyl alcohols. The term covers a class of triaryl phosphates in which three cresyl groups (from ortho-, meta-, and/or para-cresol) are bound to a central phosphate. The most hazardous member is tri-ortho-cresyl phosphate (TOCP). The generic compound has the formula C21H21O4P and a molecular weight of about 368 g/mol. TCPs are typically colorless to pale yellow, viscous liquids that are poorly soluble in water but highly soluble in organic solvents.
Production and use: TCPs are produced by esterification of cresyl alcohols with phosphorus oxychloride or related
Toxicology: TCPs are organophosphates and can inhibit acetylcholinesterase. TOCP, in particular, is a potent neurotoxin and
Environment and regulation: TCPs are lipophilic and can persist in the environment, with a tendency to accumulate
