Graphical abstract: 2-Amino-5-nitropyridinium-toluenesulfonate is identified as potential candidate for efficient frequency conversion. Research highlights: {yields} Single crystals of 2A5NPT have been grown from saturated solution. {yields} Powder test with Nd:YAG laser radiation shows a high second harmonic generation. {yields} Single shot and multiple shot surface laser damage thresholds are determined. {yields} The thermal parameters of 2A5NPT were measured by an improved photopyroelectric technique. {yields} The high value of damage threshold is related to the specific heat of the crystal which is reasonably high. -- Abstract: Single crystals of 2-amino-5-nitropyridinium-toluenesulfonate (2A5NPT) were grown by the slow cooling method. The unit cell dimensions were determined from single crystal X-ray diffraction studies. The thermal parameters - thermal diffusivity ({alpha}), thermal effusivity (e), thermal conductivity (K) and heat capacity (C{sub p}) of 2A5NPT were measured by an improved photopyroelectric technique at room temperature. Single and multiple shot experiments performed on the grown crystals for the second harmonic of pulsed Nd:YAG laser (532 nm) show that it exhibits a high laser damage threshold which is a favorable property for nonlinear optical applications. Dielectric constant and dielectric loss of the grown crystal were evaluated for the frequency range 1 kHz-1 MHz in the temperature region 40-130 {sup o}C. Hardness values were measured using Vickers hardness measurement.
