To obtain the single crystals of DL-Norleucine Maleate (DLNM), slow evaporation solution growth technique was used. The good crystalline quality of the crystal was validated by the diffraction peaks of the Powder X-Ray diffraction techniques. The functional groups which are present in the crystal were validated by FTIR and FT Raman method. Density functional theory (DFT) computation gives optimized structure parameters of DLNM molecule. The compound is changeless thermally up to 160°C and it is illustrated by TG-DTA thermal studies. The composition of the DLNM crystal was studied by EDAX spectroscopy. NMR spectral and chemical shifts of the grown crystal of DLNM were analyzed. The study of Vickers micro hardness study leads to the hardness number (HV) evaluation and work hardening coefficient. Various dielectric parameters like AC conductivity, dielectric constant and loss energy of the sample were determined from the dielectric studies.
