Description
N-(n-Butyl)thiophosphoric triamide, commonly known as BTPT or Agrotain, is a phosphorothioic triamide registered under CAS 94317-64-3 and EC 435-740-7. It carries no assigned E-code and is also referenced in trade and technical literature as butylphosphorothioic triamide.
BTPT functions primarily as a urease inhibitor in agricultural applications, binding to the urease enzyme in soil and slowing the hydrolysis of urea-based fertilizers into ammonia. This mechanism reduces nitrogen volatilization losses, improving fertilizer efficiency. It is also investigated in catalyst and flavoring research contexts.
The compound is supplied as a white crystalline solid and is subject to REACH registration requirements for European commerce. Procurement quantities are available in technical grade suitable for agrochemical formulation. Buyers should confirm supplier documentation for REACH compliance and confirm suitability for specific end-use formulations prior to ordering.
