Tris(2-chloropropyl) thiophosphate, commonly known as TCPP, is a phosphorus-containing flame retardant that is widely used in various materials to enhance their fire resistance. It is a colorless to pale yellow liquid with a faint odor and is often employed as a safer alternative to more toxic flame retardants. TCPP functions by creating a protective char layer on the surface of materials when exposed to fire, which helps to slow down the spread of flames and smoke.

Uses

Used in Polyurethane Foam Industry:
TCPP is used as a flame retardant in polyurethane foam for enhancing fire safety. It is incorporated into the foam during the manufacturing process, providing a protective layer that reduces flammability and smoke emission.
Used in Polyester Resin Industry:
In the production of polyester resins, TCPP is utilized as a flame retardant to improve the fire resistance of the final product. Its incorporation into the resin formulation helps to create a char layer that acts as a barrier against fire, thus increasing the safety of the resin-based products.
Used in Plastic Industry:
TCPP is employed as a flame retardant in the manufacturing of various types of plastics. By adding TCPP to the plastic composition, the flammability of the plastic is reduced, making it safer for use in different applications where fire resistance is a concern.

Check Digit Verification of cas no

The CAS Registry Mumber 33712-72-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,3,7,1 and 2 respectively; the second part has 2 digits, 7 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 33712-72:
(7*3)+(6*3)+(5*7)+(4*1)+(3*2)+(2*7)+(1*2)=100
100 % 10 = 0
So 33712-72-0 is a valid CAS Registry Number.
