Single crystals of pure and thiourea substituted Glycyl-L-Alanine Hydrochloride (TU-GLAHCI) are successfully grown by slow evaporation solution growth method at constant temperature of 35°C. The effect of thiourea dopant on crystal properties has been studied. Single crystal XRD analysis confirms the structure and change in lattice parameter values for the doped crystals. The doped crystals were quantitatively analysed by EDAX analysis and the presence of thiourea was confirmed. The crystals were characterized by solubility studies, FTIR and UV-Vis-NIR techniques. Second harmonic generations for the grown crystals were confirmed using Nd:YAG laser. Thermal and mechanical stability of crystals were tested by TGA/DTA and microhardness analysis. The surface morphologies of the grown crystals were analysed by scanning electron microcope (SEM).
