i-Propylpotassium, also known as potassium isopropoxide or potassium tert-butoxide, is an organometallic compound with the chemical formula (CH3)2CHOK. It is a colorless, highly reactive, and pyrophoric solid that is sensitive to moisture and air. i-Propylpotassium is commonly used as a strong base and a nucleophile in various organic synthesis reactions, such as alkylation, deprotonation, and coupling reactions. It is typically prepared by reacting potassium metal with isopropanol or tert-butanol and is often employed in the synthesis of pharmaceuticals, agrochemicals, and other specialty chemicals. Due to its reactivity, i-Propylpotassium must be handled with extreme caution and stored under an inert atmosphere to prevent hazardous reactions.
The CAS Registry Mumber 4867-40-7 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,8,6 and 7 respectively; the second part has 2 digits, 4 and 0 respectively. Calculate Digit Verification of CAS Registry Number 4867-40: (6*4)+(5*8)+(4*6)+(3*7)+(2*4)+(1*0)=117 117 % 10 = 7 So 4867-40-7 is a valid CAS Registry Number.
