N,N'-Bis-1,1,2-trimethylpropyl-harnstoff, also known as bis(1,1,2-trimethylpropyl)urea or BTPU, is an organic compound with the chemical formula C10H22N2O. It is a colorless, crystalline solid that is soluble in organic solvents and has a melting point of approximately 65-67°C. BTPU is primarily used as a chain extender and crosslinking agent in the production of polyurethane foams, providing improved mechanical properties and flame resistance. It is also employed as a blowing agent in the manufacturing of rigid foams, offering better dimensional stability and reduced water absorption. Due to its unique chemical structure, BTPU is known for its low toxicity and environmental friendliness, making it a preferred choice in various industrial applications.
The CAS Registry Mumber 6044-96-8 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,0,4 and 4 respectively; the second part has 2 digits, 9 and 6 respectively. Calculate Digit Verification of CAS Registry Number 6044-96: (6*6)+(5*0)+(4*4)+(3*4)+(2*9)+(1*6)=88 88 % 10 = 8 So 6044-96-8 is a valid CAS Registry Number.
