α-Brom-β-nitro-styrol, also known as 2-bromo-4-nitro-styrene, is an organic compound characterized by the presence of a bromine atom at the alpha position (adjacent to the vinyl group) and a nitro group at the beta position (on the carbon atom next to the alpha position) in a styrene molecule. This yellowish crystalline solid is a valuable intermediate in the synthesis of various pharmaceuticals, agrochemicals, and other specialty chemicals. Due to its reactive functional groups, α-brom-β-nitro-styrol can undergo a range of chemical reactions, such as nucleophilic substitution, reduction, and addition reactions, making it a versatile building block in organic synthesis.
The CAS Registry Mumber 15331-22-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,5,3,3 and 1 respectively; the second part has 2 digits, 2 and 2 respectively. Calculate Digit Verification of CAS Registry Number 15331-22: (7*1)+(6*5)+(5*3)+(4*3)+(3*1)+(2*2)+(1*2)=73 73 % 10 = 3 So 15331-22-3 is a valid CAS Registry Number.
