3,4-Dichlorobenzamide (cas: 2670-38-4) belongs to amides. In primary and secondary amides, the presence of N–H dipoles allows amides to function as H-bond donors as well. Thus amides can participate in hydrogen bonding with water and other protic solvents; the oxygen atom can accept hydrogen bonds from water and the N–H hydrogen atoms can donate H-bonds. Amides can be recrystallised from large quantities of water, ethanol, ethanol/ether, aqueous ethanol, chloroform/toluene, chloroform or acetic acid. The likely impurities are the parent acids or the alkyl esters from which they have been made. The former can be removed by thorough washing with aqueous ammonia followed by recrystallisation, whereas elimination of the latter is by trituration or recrystallisation from an organic solvent.HPLC of Formula: 2670-38-4

Oxidation of substituted benzyl amines using a phenoxo-bridged dimeric nickel(II) complex: synthesis, crystal structure and catalytic activity was written by Kumar, Robin;Kumar, Ravinder;Mahiya, Kuldeep;Mathur, Pavan. And the article was included in Transition Metal Chemistry (Dordrecht, Netherlands) in 2015.HPLC of Formula: 2670-38-4 This article mentions the following:

A benzimidazole-based Schiff base ligand and its dinuclear complex [Ni2(L)2(NO3)2] where HL = [2-(2-(1H-benzo[d]imidazol-2-yl)ethylimino)methyl]phenol were synthesized. An x-ray crystallog. study showed that both the metal centers in the complex adopt a distorted octahedral geometry. Variable-temperature magnetic studies suggest that the Ni(II) centers are antiferromagnetically coupled. Cyclic voltammetry confirms that the dinickel complex retains its identity in the presence of tert-Bu hydroperoxide in the solution state. The complex was used as a catalyst for the homogeneous oxidation of substituted benzyl amines in the presence of tert-Bu hydroperoxide. The yields of these reactions depend upon the nature of the substituent in the aromatic ring. In the experiment, the researchers used many compounds, for example, 3,4-Dichlorobenzamide (cas: 2670-38-4HPLC of Formula: 2670-38-4).
