2,4,6-tribromo-benzoic acid-anhydride is a chemical compound characterized by the presence of three bromine atoms attached to the benzene ring at the 2nd, 4th, and 6th positions. This halogenated derivative of benzoic acid is known for its unique properties, which include increased lipophilicity and reactivity due to the presence of bromine atoms. The compound is often used in organic synthesis as a reagent or intermediate, particularly in the preparation of other brominated compounds and pharmaceuticals. Its anhydride form, which is the result of the loss of a water molecule from two molecules of the acid, enhances its reactivity and makes it a valuable tool in various chemical transformations. The compound's structure and properties make it a versatile building block in the synthesis of complex organic molecules, particularly those with potential applications in the fields of medicine and materials science.
The CAS Registry Mumber 1734-20-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,7,3 and 4 respectively; the second part has 2 digits, 2 and 0 respectively. Calculate Digit Verification of CAS Registry Number 1734-20: (6*1)+(5*7)+(4*3)+(3*4)+(2*2)+(1*0)=69 69 % 10 = 9 So 1734-20-9 is a valid CAS Registry Number.
