[1,1'-Biphenyl]-2-diazonium tetrafluoroborate is a chemical compound with the molecular formula C12H9BF4N2. It is derived from 1,1'-biphenyl, a type of biaryl compound consisting of two phenyl rings connected by a single bond. The diazonium group (-N2+) is attached to the second carbon atom of the biphenyl structure, and the compound is stabilized by the presence of a tetrafluoroborate counterion (BF4-). [1,1'-biphenyl]-2-diazonium tetrafluoroborate is often used as a reagent in organic synthesis, particularly in the formation of aryl-aryl bonds through the Ullmann coupling reaction. It is also known for its potential applications in the synthesis of various organic compounds and materials, such as pharmaceuticals and functional materials. Due to its reactivity, it is important to handle [1,1'-biphenyl]-2-diazonium tetrafluoroborate with care, following appropriate safety protocols.
The CAS Registry Mumber 318-13-8 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 3,1 and 8 respectively; the second part has 2 digits, 1 and 3 respectively. Calculate Digit Verification of CAS Registry Number 318-13: (5*3)+(4*1)+(3*8)+(2*1)+(1*3)=48 48 % 10 = 8 So 318-13-8 is a valid CAS Registry Number.
