Carbazole-3-diazonium chloride is a chemical compound with the formula C12H10N3+Cl-. It is derived from carbazole, a tricyclic aromatic compound, by diazotization, a chemical reaction that converts an amine into a diazonium compound. The diazonium group (-N2+) is introduced at the 3-position of the carbazole ring, and the compound is then treated with hydrochloric acid to form the chloride salt. Carbazole-3-diazonium chloride is a yellow crystalline solid that is sensitive to light and heat, and it is commonly used as an intermediate in the synthesis of various dyes, pigments, and other organic compounds. Due to its reactivity, it is important to handle carbazole-3-diazonium ; chloride with care, typically under controlled conditions and in the presence of appropriate safety measures.
The CAS Registry Mumber 4858-50-8 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,8,5 and 8 respectively; the second part has 2 digits, 5 and 0 respectively. Calculate Digit Verification of CAS Registry Number 4858-50: (6*4)+(5*8)+(4*5)+(3*8)+(2*5)+(1*0)=118 118 % 10 = 8 So 4858-50-8 is a valid CAS Registry Number.
