|Section2= |Section7= }} Tetrakis(hydroxymethyl)phosphonium chloride (THPC) is an organophosphorus compound with the chemical formula ()Cl. The cation P(CH2OH)4+ is four-coordinate, as is typical for phosphonium salts. THPC has applications as a precursor to fire-retardant materials.〔Svara, Jürgen; Weferling, Norbert ; Hofmann, Thomas. Phosphorus Compounds, Organic. Ullmann's Encyclopedia of Industrial Chemistry. John Wiley & Sons, Inc, 2008 〕 ==Synthesis and reactions== THPC can be synthesized with high yield by treating phosphine with formaldehyde in the presence of hydrochloric acid.〔 :PH3 + 4 H2C=O + HCl → ()Cl THPC is commonly used to prepare tris(hydroxymethyl)phosphine by treating it with aqueous sodium hydroxide.〔M.
