Perylen-3-carbonsaeure-chlorid, also known as perylene-3-carboxylic acid chloride, is a chemical compound with the molecular formula C16H7ClO3. It is a derivative of perylene, a polycyclic aromatic hydrocarbon, and is characterized by the presence of a carboxylic acid group and a chlorine atom. Perylen-3-carbonsaeure-chlorid is often used as an intermediate in the synthesis of various dyes, pigments, and other organic compounds due to its unique chemical properties. It is typically synthesized through the reaction of perylene-3,4-dicarboxylic acid with thionyl chloride, resulting in the formation of the desired perylene-3-carboxylic acid chloride. The compound is sensitive to moisture and should be stored under anhydrous conditions to maintain its stability.
The CAS Registry Mumber 7350-89-2 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 7,3,5 and 0 respectively; the second part has 2 digits, 8 and 9 respectively. Calculate Digit Verification of CAS Registry Number 7350-89: (6*7)+(5*3)+(4*5)+(3*0)+(2*8)+(1*9)=102 102 % 10 = 2 So 7350-89-2 is a valid CAS Registry Number.
