N-(n-Butyl)thiophosphoric triamide (NBPT) is the organophosphorus compound with the formula SP(NH₂)₂(NHC₄H₉). It is an amide of thiophosphoric acid. A white solid, NBPT is an "enhanced efficiency fertilizer", intended to limit the release of nitrogen-containing gases following fertilization.{{cite journal |doi=10.1016/j.agee.2017.10.008|title=A re-evaluation of the agronomic effectiveness of the nitrification inhibitors DCD and DMPP and the Urease Inhibitor NBPT|year=2018|last1=Rose|first1=Terry J.|last2=Wood|first2=Rachel H.|last3=Rose|first3=Michael T.|last4=Van Zwieten|first4=Lukas|journal=Agriculture, Ecosystems & Environment|volume=252|pages=69–73|bibcode=2018AgEE..252...69R }} Regarding its chemical structure, the molecule features tetrahedral phosphorus bonded to sulfur and three amido groups.
