Tetrakis (hydroxymethyl) phosphonium chloride (THPC) Application

Tetrakis (hydroxymethyl) phosphonium chloride (THPC) CAS:124-64-1 is an organic phosphorus compound with a variety of industrial applications, mainly in the following areas:

1. Flame retardants

-Textile treatment: THPC is widely used in permanent flame retardant finishing of cotton, polyester and other fabrics. The polymer formed by reaction with urea, melamine and other compounds can be firmly attached to the fiber, giving the material wash-resistant flame retardant properties (such as Nomex protective clothing).

-Foam materials: Some polyurethane foam materials are treated with THPC to improve fire resistance.

2. Antimicrobial agents and preservatives

-Industrial water treatment: used for cooling tower, paper mill and other systems to kill algae, inhibit the growth of microorganisms.

-Wood preservation: Treatment of wood to prevent fungal and insect infestation.

3. Chemical intermediates

-Used to synthesize other organophosphorus compounds, such as tetramethylenesulfonic phosphoric acid (THPS), which is also an environmentally friendly bactericide and flame retardant.

4. Other uses

-Oilfield chemistry: used as corrosion inhibitor or bactericide in some oilfield applications.

-Laboratory reagents: used as phosphorus source or crosslinking agent in organic synthesis.

 Attention ：

-THPC is irritating and should be handled with care to avoid contact with skin or inhalation.

-Partial applications (such as flame retardant finishing) may involve formaldehyde release and need to comply with environmental regulations (such as REACH, OEKO-TEX® standards).

If you need more specific application details (such as the formula process of a certain product), it is recommended to consult professional literature or industry standards.
