1-p-tolyl-1H-pyrazol-3-amine is an organic compound with the molecular formula C10H12N2. It is a derivative of pyrazole, a five-membered heterocyclic ring containing three nitrogen atoms, and is characterized by the presence of a p-tolyl group (a methyl group attached to a phenyl ring) at the 1-position. 1-p-tolyl-1H-pyrazol-3-amine is a white crystalline solid and is used as a building block in the synthesis of various pharmaceuticals and agrochemicals due to its potential biological activities. It is also known for its potential applications in the development of new materials and as a ligand in coordination chemistry. The compound's properties, such as solubility and reactivity, can be influenced by the presence of the p-tolyl group, making it a versatile intermediate in organic synthesis.

87949-14-2 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 87949-14-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,7,9,4 and 9 respectively; the second part has 2 digits, 1 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 87949-14:
(7*8)+(6*7)+(5*9)+(4*4)+(3*9)+(2*1)+(1*4)=192
192 % 10 = 2
So 87949-14-2 is a valid CAS Registry Number.

Nickel-catalyzed Chan-Lam cross-coupling: Chemoselective: N -arylation of 2-aminobenzimidazoles

Kumar, K. Anil,Kannaboina, Prakash,Rao, D. Nageswar,Das, Parthasarathi

, p. 8989 - 8997 (2016/10/05)

A complementary set of Ni- and Cu-based catalyst systems for the selective N-arylation of 2-aminobenzimidazoles have been developed. Selective N-arylation of the primary amine (C-NH2) group was achieved by Ni-catalyzed, boronic acid promoted cr

Copper(I)/Copper(II)-Assisted Tandem Catalysis: The Case Study of Ullmann/Chan-Evans-Lam N1,N3-Diarylation of 3-Aminopyrazole

Beyer, Astrid,Castanheiro, Thomas,Busca, Patricia,Prestat, Guillaume

, p. 2433 - 2436 (2015/08/24)

Unprecedented CuI/CuII-assisted tandem catalysis allowing an Ullmann/Chan-Evans-Lam sequence was achieved. This three-component, one-pot reaction triggered by a change in the oxidation state of the metal leads to the selective N1,N3-diarylation of 3-aminopyrazole. This new method should be a valuable tool for small-molecule drug discovery that requires suitable regio- and/or chemoselective strategies for the N-arylation of nitrogen-containing heterocycles. Tandem power: The first assisted tandem copper-catalyzed process, triggered by a change in the oxidation state of the metal, is developed to allow a one-pot Ullman/Chan-Evans-Lam sequence leading to the selective N1,N3-diarylation of 3-aminopyrazole.
