(E)-1-Methoxy-buta-1,3-dien-1-ol anion, also known as the enolate ion of (E)-1-methoxybuta-1,3-diene, is a chemical species derived from the deprotonation of the corresponding alcohol. This anion features a conjugated diene system with a methoxy group attached to the terminal carbon, and it exhibits a (E)-configuration, indicating the trans arrangement of the double bonds. The anion is generated by the removal of a proton from the hydroxyl group, resulting in a negatively charged oxygen atom. This species is of interest in organic chemistry, particularly in reactions involving nucleophilic addition and substitution, due to its ability to act as a nucleophile. The anion's reactivity and stability are influenced by the electron-donating methoxy group and the conjugated system, which can participate in resonance, thereby delocalizing the negative charge.
The CAS Registry Mumber 80462-73-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,0,4,6 and 2 respectively; the second part has 2 digits, 7 and 3 respectively. Calculate Digit Verification of CAS Registry Number 80462-73: (7*8)+(6*0)+(5*4)+(4*6)+(3*2)+(2*7)+(1*3)=123 123 % 10 = 3 So 80462-73-3 is a valid CAS Registry Number.
