Isopentyl sodium, also known as sodium 2-methylbutan-2-olate, is an organosodium compound with the chemical formula C5H11NaO. It is a colorless liquid that is soluble in water and is commonly used as a strong base and nucleophile in organic synthesis. Isopentyl sodium is prepared by reacting isopentyl alcohol with sodium metal, and it is often used in the synthesis of various organic compounds, such as esters, amides, and other derivatives. Due to its reactivity, it is typically handled under an inert atmosphere and stored away from moisture and air to prevent decomposition.
The CAS Registry Mumber 2875-34-5 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,8,7 and 5 respectively; the second part has 2 digits, 3 and 4 respectively. Calculate Digit Verification of CAS Registry Number 2875-34: (6*2)+(5*8)+(4*7)+(3*5)+(2*3)+(1*4)=105 105 % 10 = 5 So 2875-34-5 is a valid CAS Registry Number.
