Single crystal of 2-amino-4,6-dimethylpyrimidium 3,5-dinitrobenzoate dihydrate (2APDBD) was grown by solution growth technique. The X-ray diffraction reveals that 2APDBD crystal belongs to a centrosymmetric triclinic crystal system with space group P-1. The UV visible-NIR spectra confirm a peak at 350 nm with lower cut off wavelength shows a wide transmission window in the entire visible region. The electrical characteristics of 2APDBD crystal have a low density of defects and a low value of dielectric loss found from the dielectric studies.  To find out the third order nonlinear susceptibilities (χ(3)) Z-can analysis was used.
