55566-30-8
Product Name: Tetrakis(hydroxymethyl)phosphonium Sulfate
English Alias: THPS; Tetrahydroxymethylphosphonium sulfate
CAS Number: 55566-30-8
Molecular Formula: C₄H₁₂O₈P₂S
Molecular Weight: 274.16 g/mol
Appearance: Colorless to pale yellow transparent liquid
Package: 25 kg/drum, 200 kg/drum (HDPE plastic drum)
Tetrakis(hydroxymethyl)phosphonium Sulfate (THPS) is a quaternary phosphonium salt appearing as a colorless to pale yellow transparent liquid. It is fully soluble in water and polar solvents. The compound is widely recognized as an effective biocide, flame retardant, and reducing agent. It exhibits low environmental persistence and toxicity profile compared to traditional biocides, making it suitable for various industrial applications.
Item | Indicator |
THPS content% ≥ | 75 |
Viscosity (25°C) MPA·S | 30.0-36.0 |
Relative density (25°C) | 1.350-1.420 |

Oil and gas industry:Tetrakis(hydroxymethyl)phosphonium Sulfate used to control the growth of sulfate-reducing bacteria and prevent MIC in drilling and extraction operations.
Water treatment: Applied in industrial cooling systems and other water treatment processes.
Textiles:Tetrakis(hydroxymethyl)phosphonium Sulfate used in the production of flame-retardant and crease-resistant finishes for fabrics.
Paper industry: Used as an antimicrobial agent in paper manufacturing
Tetrakis(hydroxymethyl)phosphonium Sulfate causes skin and eye irritation. May cause respiratory irritation. Use appropriate personal protective equipment including gloves, safety glasses, and adequate ventilation when handling. Avoid contact with skin and eyes. The substance is harmful to aquatic life. For detailed safety information, always consult the full Safety Data Sheet (SDS).
Store in a cool, dry, well-ventilated area away from direct sunlight. Keep containers tightly closed and sealed. Maintain storage temperature between 5-30°C. Keep away from strong oxidizing agents and alkaline materials.
Tetrakis(hydroxymethyl)phosphonium Sulfate is packaged in HDPE plastic drums (25 kg or 200 kg net weight per drum). Transport as non-hazardous material under normal conditions. Ensure containers are properly sealed and protected from physical damage during transportation. Store away from incompatible materials.
