1. Product Information & Specifications

Monopotassium Phosphite (CAS 13977-65-6), with the chemical formula KH₂PO₃, is a highly soluble potassium-phosphorus compound widely used in agriculture, industrial processes, and research. Below are its key parameters:

*MKP = Monopotassium Phosphate (KH₂PO₄)

2. Detailed Applications

Agricultural Uses

• Fungicide: Triggers plant systemic acquired resistance (SAR) against pathogens like Phytophthora and Pythium.
• Fertilizer: Supplies potassium (K⁺) and phosphite (PO₃^3-) for root development and stress tolerance.
• Soil Amendment: Impro phosphate availability in alkaline soils.

Industrial Uses

• Water Treatment: Prevents scale formation in cooling towers.
• Fire Retardants: Synergist in intumescent coatings.

Research Uses

• Studying phosphite-mediated plant immunity pathways.
• Nutrient uptake efficiency trials.
