Potassium naphthalene anion radical, also known as potassium naphthalenide, is a chemical compound with the formula C10H8K2. It is formed when naphthalene, a polycyclic aromatic hydrocarbon, undergoes a one-electron reduction process, resulting in the formation of a radical anion. potassium naphthalene anion radical is typically generated in the presence of a strong reducing agent, such as potassium metal, and is often used in organic synthesis as a reagent for the introduction of the naphthalene ring system into various organic molecules. The potassium naphthalene anion radical is characterized by its ability to act as a nucleophile and participate in various chemical reactions, such as electrophilic aromatic substitution and coupling reactions. Due to its unique electronic properties and reactivity, it has found applications in the synthesis of complex organic molecules and materials with potential uses in pharmaceuticals, agrochemicals, and other industrial sectors.
The CAS Registry Mumber 4216-48-2 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,2,1 and 6 respectively; the second part has 2 digits, 4 and 8 respectively. Calculate Digit Verification of CAS Registry Number 4216-48: (6*4)+(5*2)+(4*1)+(3*6)+(2*4)+(1*8)=72 72 % 10 = 2 So 4216-48-2 is a valid CAS Registry Number.
