Product Description

Structural Formula:

Tetrakis-Hydroxymethyl Phosphonium Chloride (THPC)

CAS #: 124-64-1
EINECS #: 204-707-7
Molecular Formula: (CH2OH)4PCl

Properties:

The primary benefit of THPC is its low toxicity, which makes it safe to use around humans, animals and plants. This makes it ideal for many industrial applications, such as fire retardants and biocides, where hazardous materials may exist. Additionally, its rapid environmental breakdown ensures that it will not accumulate or persist in the environment, making it a safe solution for long-term applications without fear of contamination or pollution. Lastly, THPC exhibits excellent solubility in organic and aqueous solutions because of its four-coordinate properties as a phosphonium salt.

Applications

THPC can be used in multiple industries with tremendous efficiency. As an effective fire retardant material for textile production, THPC has been found to reduce flammability without compromising fabric integrity or colourfastness during use. This versatile compound can also control microbial growth in water systems; as an active micro biocide, it can quickly eradicate bacteria while being relatively safe enough not to affect humans or wildlife adversely. Finally, THPC can also be used as an effective sanitiser against germs and viruses without leaving unwanted residues or odours due to its low toxicity levels.
