Urea, N,N''-1,3-propanediylbis[N,N'-diphenyl-], also known as bis(N,N-diphenyl)urea or BDPU, is an organic compound with the chemical formula C21H20N2O. It is a white crystalline solid that is soluble in organic solvents and has a molecular weight of 316.4 g/mol. BDPU is primarily used as a flame retardant and smoke suppressant in various polymers, such as polyurethane foams, polyamides, and polyesters. It works by releasing non-flammable gases and forming a char layer when exposed to heat, which helps to slow down the combustion process. Additionally, BDPU has been studied for its potential applications in pharmaceuticals and as a precursor in the synthesis of other organic compounds.

35385-98-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 35385-98-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,5,3,8 and 5 respectively; the second part has 2 digits, 9 and 8 respectively.Calculate Digit Verification of CAS Registry Number 35385-98:
(7*3)+(6*5)+(5*3)+(4*8)+(3*5)+(2*9)+(1*8)=139
139 % 10 = 9
So 35385-98-9 is a valid CAS Registry Number.
