A Convenient Route to Synthesize and Grow 2-Amino 5-Nitro Pyridinium Nitrate Crystals for Laser Generation

An organic nonlinear optical (NLO) crystaline salt 2-Amino 5-Nitro Pyridinium Nitrate (2A5NPN) was ucesfuly synthesized from Pyridine. From Pyridine, we have synthesized 3-Nitro Pyridine (3NP).3-Nitro Pyridine (3NP) with reaction of Ammonia on KMnO4 The as obtained synthesized salt of 2-Amino 5-Nitro Pyridine(2A5NP) was mixed with concentrated Nitric acid with apropriate stochiometric ratio to obtain 2-Amino 5-Nitro Pyridinium Nitrate(2A5NPN). The synthesized 2-Amino 5-Nitro Pyridinium Nitrate (2A5NPN) was taken for solubilty studies. Based on the solubilty study, atempts wil be made to grow single and bulk crystals of 2-Amino 5-Nitro Pyridinium Nitrate (2A5NPN) by slow evaporation method and by using asembled temperature reduction aparatus technique. The powdered sample of 2-Amino 5-Nitro Pyridinium Nitrate (2A5NPN) confirmed the second harmonic generation (SHG) using Nd:YAG laser.
