Structural Formula:

Property:

Tetrakis(Hydroxymethyl)Phosphonium Sulfate(THPS) is a kind of environmental anti-microbial reagent. THPS is characterized by its low solidity point and fine stability. Tetrakis(Hydroxymethyl)Phosphonium Sulfate(THPS) can be reserved for long time and can easily dissolve in water. Tetrakis(Hydroxymethyl)Phosphonium Sulfate(THPS) is a kind of new environmental pesticide with high efficacy, low toxicity and low rudimental. Tetrakis(Hydroxymethyl)Phosphonium Sulfate(THPS) can kill germ and aquatic plants. In 1995, the EPA of the United States ratified it with zero toxicity and awarded it with US Green Chemical prize.
