Applications

• Flame - Retardant Materials

. In nanochemistry, it serves as a reductant and stabilizer for nanoparticles. It can also be used as a cross - linker to tune the properties of protein - based hydrogels for 3D cell encapsulation applications

Advantages

THPC is a new - type antimicrobial agent with low toxicity, low dosage requirements, and rapid breakdown in the environment, causing minimal impact on the environment.

Hazards

• Corrosiveness: It is a corrosive liquid

. Appropriate protective measures should be taken during use to ensure safety.

• : It is a key ingredient in commercial flame - retardant formulations, widely used in the textile industry to make flame - resistant fabrics for protective clothing. It is also used in the wood industry to enhance the fire resistance of lumber and plywood, and in the paper industry for fire - resistant paper products.

• Microbiocide

• : It can be used to control bacteria, algae, and fungi in industrial and commercial recirculating cooling water systems, heat transfer water systems, and industrial process water systems. It is also used in the oilfield to control bacterial growth.

• Other Applications: In the leather industry, it is used as a tanning agent

• . Contact with skin and eyes should be avoided to prevent irritation and damage.

• Toxicity: It is toxic if ingested or inhaled
