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, 1,4-Bis-<4-nitro-phenoxy>-but-2t-en 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.
