Benzolphosphonsaeure-bis-(n-propyloxycarbonyl-amid), also known as benzene phosphonic acid bis(n-propyloxycarbonylamide), is a complex organic compound with the chemical formula C??H??N?O?P. It is a white crystalline solid that is soluble in water and various organic solvents. Benzolphosphonsaeure-bis-(n-propyloxycarbonyl-amid) is primarily used as a flame retardant and plasticizer in the production of polymers, particularly in the manufacturing of polyvinyl chloride (PVC) and other plastics. Its flame-retardant properties are attributed to the phosphorus content, which helps to char the material and reduce the release of flammable gases when exposed to heat or fire. Additionally, benzene phosphonic acid bis(n-propyloxycarbonylamide) can act as a plasticizer, improving the flexibility and workability of plastics. Due to its versatility and effectiveness, it is widely used in various industries, including construction, automotive, and electronics.
The CAS Registry Mumber 4450-49-1 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,4,5 and 0 respectively; the second part has 2 digits, 4 and 9 respectively. Calculate Digit Verification of CAS Registry Number 4450-49: (6*4)+(5*4)+(4*5)+(3*0)+(2*4)+(1*9)=81 81 % 10 = 1 So 4450-49-1 is a valid CAS Registry Number.
