2,3-Diamino Pyridine Research Reports

2,3-Diamino Pyridine Research Reports

Pyridine and its derivatives such as 2, 3 diamino pyridine play an important role in the heterocyclic chemistry. They are often involved in hydrogen-bond interactions. 2, 3 diamino pyridine is also known as pyridine, 2, 3-diamino; 2, 3-DiaMinopyridine; di-amino pyridine; and 2, 3-Pyridinediamine. It has an appearance of slightly beige powder. 2, 3 diamino pyridine is stable under normal pressures and temperatures. 2, 3 diamino pyridine is completely soluble in water. It is supposed to be stored in refrigerators at +4 degree Celsius. The compound is used for the synthesis of 2, 3-Diaminopyridinium 4-hydroxybenzonate. It is used as an internal standard in the analysis of poly amidoamine dendrimers displaying different terminal functionalities by capillary electrophoresis. 2, 3 diamino pyridine is used as a reagent in the synthesis of organometallic compounds and imidazopyridines. It is also used in the two step solution polymerization process to prepare novel polyurethane urea containing pyridine moieties in its main chains.

Different cross linkers, along with 2, 3 diamino pyridine and chain extending isocyanate end capped prepolymers are used to synthesize polyurethane urea. The use of pyridine derivatives such as 2, 3 diamino pyridine in the structural composition of polyurethane urea leads to changes in its properties that were previously investigated using Fourier Transform Infrared Spectroscopy (FT-IR), mechanical measurements, thermogravimetric analysis (TGA), contact angle, differential scanning calorimetry (DSC), and fluorescence analysis. These properties of urethane groups are influenced if synthesized using 2, 3 diamino pyridine or similar pyridine derivatives due to forming of intermolecular hydrogen bonds between two compounds.

2, 3 diamino pyridine can also be used to derive two new Schiff bases by synthesis with pyrrole-2-carboxaldehyde (Pyrr) and 2-hydroxy-1-naphthaldehyde (NaphH), and iron (III), ruthenium (II), new copper (II), nickel (II) along with zinc (II) complexes (1b) - (1-e), (2b) - (2f), and (3b) – (3d). These new Schiff bases are characterized by magnetic susceptibility, NMR Spectra, elemental analyses, and IR spectra. These new bases created with 2, 3 diamino pyridine also display certain antibacterial activity.
