9-Fluorenylpotassium, also known as 9-fluorenylidenekopotassium or 9-fluorenylidenepotassium, is an organometallic compound with the chemical formula C13H7K. It is a highly reactive and sensitive reagent, often used in organic synthesis as a strong base and a nucleophile. The compound is derived from fluorene, a polycyclic aromatic hydrocarbon, and potassium metal. Due to its reactivity, 9-fluorenylpotassium is typically generated in situ and used immediately to avoid decomposition. It plays a crucial role in various chemical reactions, such as the synthesis of fluorene-based polymers and the formation of carbon-carbon bonds, making it an important tool in the field of organic chemistry.
The CAS Registry Mumber 7307-10-0 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 7,3,0 and 7 respectively; the second part has 2 digits, 1 and 0 respectively. Calculate Digit Verification of CAS Registry Number 7307-10: (6*7)+(5*3)+(4*0)+(3*7)+(2*1)+(1*0)=80 80 % 10 = 0 So 7307-10-0 is a valid CAS Registry Number.
