What Is Tetrakis(hydroxymethyl)phosphonium Sulfate (THPS 75%)?
Identity and Form
THPS 75% is an aqueous solution of tetrakis(hydroxymethyl)phosphonium sulfate, CAS 55566-30-8. The phosphonium sulfate salt differs from tetrakis(hydroxymethyl)phosphonium chloride. Compare solution concentration and chemical identity when choosing a grade for process or formulation development.
Grade and Quality Checks
The supply grade specifies assay ≥75.1%, pH 3.0–5.0, viscosity 30–36 mPa·s at 25°C, relative density 1.350–1.420 and iron ≤15 mg/kg. Preserve the test temperature and solution basis when comparing these values with another concentration or supplier grade.
Application Selection
Authorized industrial microbial-control applications can include selected water, oilfield and paper-process systems. Evaluate dosing, contact conditions, water chemistry, process compatibility and effluent management against the applicable registered use. A raw-material specification does not establish efficacy or authorization for a finished biocidal product.
Packing and Handling
Selected textile flame-retardant treatment systems require independent assessment of recipe compatibility, curing, wash durability and final-article performance. Control liquid splashes and aerosols. The matched 75% aqueous transport reference is Class 8 with subsidiary risk 6.1, UN 2922, packing group III.
