Description

n-(n-Butyl)Thiophosphoric Triamide (NBPT) is a highly effective urease inhibitor used to enhance the efficiency of urea-based fertilizers. This compound is critical for reducing nitrogen loss through ammonia volatilization, thereby increasing nutrient availability for crops and minimizing environmental impact. It is an essential component for agricultural formulators, fertilizer producers, and research institutions focused on developing advanced, sustainable agrochemical solutions.

Application

• Urease Inhibitor in Agriculture: Primary use as an additive in urea and urea-ammonium nitrate (UAN) fertilizers to slow the hydrolysis of urea, reducing ammonia emissions and improving nitrogen use efficiency.
• Fertilizer Coating Agent: Applied as a coating on granular or prilled urea to create enhanced-efficiency fertilizers (EEFs) for controlled-release applications.
• Agrochemical Intermediates: Serves as a key intermediate in the synthesis of more complex thiophosphoric triamide derivatives for specialized agricultural uses.
• Research & Development: Used in academic and industrial R&D for studying nitrogen cycle dynamics, soil chemistry, and the development of next-generation nutrient management technologies.
• Industrial Catalyst Systems: Investigated for potential use in specific catalytic processes within specialty chemical manufacturing.
