Used as a flame retardant in textiles and plastics due to its ability to release water and form protective char layers when exposed to heat. Employed in agricultural formulations as a stabilizer for pesticides and as an intermediate in producing sulfur-containing phosphate fertilizers to enhance nutrient absorption in sulfur-deficient soils. Its hydrate structure contributes to moisture retention in specific industrial processes. Utilized in chemical synthesis as a source for thiophosphate groups and controlled release of sulfur or phosphorus species. Also applied in wastewater treatment to bind heavy metals.
