Chemical Properties Of N-(n-butyl)thiophosphoric triamide Cas 94317-64-3

Cas 94317-64-3 (NBPT) is a triamide derivative of phosphorothioic acid, MF: C4H14N3PS, MW: 167.21. It is typically a white crystalline solid and is the most widely used highly effective urease inhibitor globally. Its primary function is to inhibit urease activity in soil, thereby reducing ammonia volatilization losses from urea fertilizers and improving nitrogen fertilizer utilization. It is also used in fine chemical synthesis and metal protection applications.

Product Application Of N-(n-butyl)thiophosphoric triamide Cas 94317-64-3

  1. Core Agricultural Applications:
    – Acts as a urease inhibitor when added to urea and compound fertilizers, suppressing soil urease activity, reducing ammonia volatilization and loss, and significantly improving nitrogen fertilizer utilization.
    – Used to formulate long-lasting, stable, controlled-release fertilizers, extending the fertilizer’s effective period, reducing the frequency of top-dressing, and saving on labor costs.
    – Prevents high-concentration ammonia generated by rapid urea decomposition from damaging seeds and seedlings, thereby improving germination rates and seedling survival rates.
    – Suitable for various crops, including grain crops, vegetables, melons and fruits, and orchard trees—particularly well-suited for alkaline soils, helping to increase crop yields and improve quality.
    – Easily biodegradable with no residues; does not harm beneficial soil microorganisms, making it suitable for green and ecological agriculture.

  2. Chemical and Other Applications:
    – Used as an organic synthesis intermediate for the preparation of fine chemical derivatives containing phosphorus and sulfur structures.
    – Can serve as a raw material for the synthesis of polymer additives and metal surface corrosion inhibitors.
