1-Propen-1-ol, 1-methoxy-, lithium salt, (E)- is a chemical compound with the molecular formula C4H7LiO2. It is a derivative of allyl alcohol, where the hydroxyl group (-OH) is replaced by a methoxy group (-OCH3), and the double bond is in the (E)-configuration, indicating the trans arrangement of the substituents around the double bond. This lithium salt is formed by the reaction of 1-methoxy-1-propen-1-ol with lithium hydroxide, resulting in a compound that can be used as a reagent in organic synthesis, particularly in the formation of various organic compounds through nucleophilic substitution reactions. The lithium salt form of 1-Propen-1-ol, 1-methoxy-, lithium salt, (E)- is advantageous due to its increased solubility and reactivity compared to its non-metallated counterpart.
The CAS Registry Mumber 72657-81-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,2,6,5 and 7 respectively; the second part has 2 digits, 8 and 1 respectively. Calculate Digit Verification of CAS Registry Number 72657-81: (7*7)+(6*2)+(5*6)+(4*5)+(3*7)+(2*8)+(1*1)=149 149 % 10 = 9 So 72657-81-9 is a valid CAS Registry Number.
