It is a pale yellow solid with a melting point of 105-107 °C and is considered to be potentially hazardous due to its irritant and toxic properties. 3-Methyl-3'-nitro-1,1'-biphenyl is primarily used in research and industrial applications.
Check Digit Verification of cas no
The CAS Registry Mumber 952-03-4 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 9,5 and 2 respectively; the second part has 2 digits, 0 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 952-03:
(5*9)+(4*5)+(3*2)+(2*0)+(1*3)=74
74 % 10 = 4
So 952-03-4 is a valid CAS Registry Number.

New synthesis of biaryls via Rh-catalyzed decarbonylative Suzuki-coupling of carboxylic anhydrides with arylboroxines
Goossen,Paetzold
, p. 1665 - 1668 (2007/10/03)
The catalytic cross-coupling of aromatic carboxylic anhydrides or acid chlorides with triarylboroxines has been achieved for the first time under decarbonylation, giving rise to the unsymmetrical biaryls rather than the expected diaryl ketones. This new decarbonylative Suzuki coupling, catalyzed by a [Rh(ethylene)2Cl]2/KF system, can be applied to aromatic, heteroaromatic and vinylic carboxylic anhydrides, potentially opening up new perspectives for the use of carboxylic acid derivatives as substrates in biaryl syntheses.
