Tetrakis(hydroxymethyl)phosphonium Sulfate (THPS), identified by CAS number 55566-30-8, is a versatile organophosphorus compound with a unique set of chemical properties that enable its widespread use across various industries. While its primary recognition comes from its potent biocidal capabilities, THPS also exhibits characteristics that make it valuable as a flame retardant and a functional agent in chemical synthesis.

Chemically, THPS is a salt formed from tetrakis(hydroxymethyl)phosphonium cation and sulfate anion. Its molecular formula is C8H24O12P2S, and it typically exists as a clear, colorless to light yellow liquid solution with an assay of ≥75%. Key properties include a specific gravity between 1.35-1.42 at 25°C, a viscosity of 30-40 cps at 25°C, and a pH range of 2.5-5.5. Its excellent water solubility and low solidification point contribute to its ease of handling and application in aqueous systems.

The chemical stability of THPS under various conditions is a significant advantage. It remains effective in a broad pH range and is compatible with many other water treatment chemicals. Furthermore, its biodegradability is a critical environmental attribute, distinguishing it from many older biocidal chemistries.

Beyond its role in water treatment and oilfield operations, THPS's utility extends to the textile industry, where it functions as a durable flame retardant for cellulosic materials. Its ability to form stable char layers upon heating inhibits fire spread, offering a safer alternative to halogenated compounds. In the leather industry, it serves as a chrome-free tanning agent, improving the quality and sustainability of leather production.
