| Hazard Information | Back Directory | [Description]
Oxamic acids also known to as oxalic acid monoamides have emerged as potent precursors for the generation of the carbamoyl radical. Oxamic acids can easily undergo decarboxylation through a single electron oxidation resulting in the generation of the reactive carbamoyl radical, which can then engage in diverse radical reactions or undergo a second single electron oxidation as originally unveiled by Minisci. Oxamic acids are thus versatile intermediates for the synthesis of nitrogen-containing organic molecules[1]. The oxidative decarboxylation of oxamic acids can be mediated through thermal, photochemical, electrochemical or photoelectrochemical means, generating carbamoyl radicals, which may further add to unsaturated systems to provide a broad range of important amides. Oxidative decarboxylation of oxamic acids also offers a straightforward entry for the preparation of urethanes, ureas, and thioureas.

Oxamic acid is an ozone oxidation product and is used in the synthesis of hydroxybenzimidazoles preparation as potential anti tumor agents targeting human lactate dehydrogenase A.This compound is suitable for lactate dehydrogenase (LDH) related research. | [Application]
Oxamic acid (OA) has applications in polymer chemistry. It increases the water solubility of certain polymers, including polyester,epoxide, and acrylic upon binding with them. Oxamic acid can be used as a reactant to prepare 6-phenanthridinecarboxamide by direct C-H carbamoylation reaction using ammonium persulfate in DMSO. It can also be used as an organic ligand to prepare functionalized metal oxide nanoparticles for various biological applications. OA along with p-aminobenzoic acid is used to functionalize Au nanoparticles for the development of a sensor to detect Fe3+ ions by the calorimetric method. | [Definition]

The final unit-cell parameters of oxamic acid are a = 9.4989 (6), b = 5.43796 (9), c = 6.8637 (9) Å, β = 107.152 (5), V = 338.772 (10) Å3 , Z = 4. The refinement converged to the figures of merit: Re = 0.01674, Rp = 0.03270, Rwp = 0.05652 and GoF = 3.378 with a good fit between the calculated pattern of the structural model and the experimental pattern. The DFT-D calculations show an excellent reproduction of the experimental structure, validating the correctness of the structure. The non-centrosymmetric nature of the structure was confirmed by SHG measurements. In the crystal structure, the molecules are close to planar and form a complex 2D hydrogen-bonding pattern based on the cyclic amide-acid heterosynthon.
