Is THPS the same substance as Tetrakis(hydroxymethyl)phosphonium sulfate?

Yes. THPS is the common abbreviation for Tetrakis(hydroxymethyl)phosphonium sulfate, CAS 55566-30-8. The offered liquid should still be matched by active content, pH, density, iron level, packaging and the intended industrial treatment program.

Is THPS 75% supplied as a finished cooling-water, injection-water or oilfield treatment program?

No. THPS 75% is an industrial active raw material used in selected formulated programs. The finished treatment approach depends on the system water chemistry, other additives, dosage, contact conditions, materials compatibility and applicable requirements.

Which THPS information should be confirmed before an industrial treatment-formulation order?

Confirm active content, appearance, colour, pH, relative density, iron, viscosity, packaging and the intended program. The batch COA, product TDS and SDS should correspond to the agreed THPS 75% grade and relevant local requirements.

Tetrakis(hydroxymethyl)phosphonium Sulfate (THPS) CAS 55566-30-8

Tetrakis(hydroxymethyl)phosphonium sulfate (THPS), CAS 55566-30-8, is a water-soluble quaternary phosphonium salt supplied as a 75% liquid for industrial water-treatment systems, oilfield operations and selected process formulations. Also known as THPS, it is an industrial active raw material rather than a finished treatment program. Selection depends on water chemistry, treatment design, materials compatibility, contact conditions and applicable local requirements. Commercial lots should be matched by active content, appearance, colour, pH, relative density, iron, viscosity and packaging. Batch COA, TDS and SDS can be reviewed against the agreed 75% industrial grade.

Product Introduction

Tetrakis(hydroxymethyl)phosphonium Sulfate (THPS) (CAS 55566-30-8) is an aqueous industrial active used in water-treatment, oilfield and paper-process formulations. This page covers THPS 75% solution for downstream industrial treatment programs; it is not a ready-to-dose field product or a complete microbiological-control program.

Applications

Industrial water-treatment and process-water formulations
Oilfield injection-water, drilling, completion and production-treatment programs
Paper-manufacturing process formulations where THPS is specified
Specialty industrial systems requiring a THPS aqueous-active component

Solution Grade and Documentation

The offered solution is confirmed against the required THPS active content, pH, density, iron limit and the stated industrial application. A batch COA, with the applicable TDS and SDS, is available for the quoted grade. Packaging and quantity are selected for the agreed industrial process and applicable shipment requirements.
