1,4-Bis-<4-nitro-phenoxy>-but-2-en, also known as 1,4-bis(4-nitrophenoxy)-2-butene, is an organic compound characterized by a butene backbone with two 4-nitrophenoxy groups attached to the 1 and 4 positions. This molecule is a yellow crystalline solid and is often used as a chemical intermediate in the synthesis of various pharmaceuticals and agrochemicals. The presence of the nitro groups and the butene double bond make it a versatile building block for the formation of complex molecules. It is important to note that due to the presence of nitro groups, this compound may be sensitive to heat and friction, and appropriate safety measures should be taken during its handling and storage.
The CAS Registry Mumber 6728-07-0 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,7,2 and 8 respectively; the second part has 2 digits, 0 and 7 respectively. Calculate Digit Verification of CAS Registry Number 6728-07: (6*6)+(5*7)+(4*2)+(3*8)+(2*0)+(1*7)=110 110 % 10 = 0 So 6728-07-0 is a valid CAS Registry Number.
