Objectives: To evaluate the optical properties of the trimethoprim (TMP) single crystal. Methods: 5-(3, 4, 5- trimethoxybenzyl) pyrimidine-2-4-diamine known as trimethoprim (TMP), a single crystal is a well-known antibiotic drug, was grown by the slow evaporation method. Findings: The TMP unit cell parameters were confirmed by single crystal X-ray diffraction. Functional groups of TMP crystal was confirmed by Fourier transform infrared spectral analysis. The optical spectrum shows the wide transparency window of TMP which is the prerequisite for NLO material. The band gap is calculated as 4.10 eV from Tauc’s plot. The various optical constants like extinction coefficient, refractive index and reflectance were calculated from the transmittance spectrum data. The optical and electrical parameters like optical conductivity, electrical conductivity and susceptibility of the single crystal of TMP were determined from the UV spectrum. The fluorescence spectrum shows the presence of a sharp intense peak at 690 nm indicates red emission and a weak peak observed at 480 nm indicates blue emission. The Vickers hardness study shows the grown crystal belongs to the soft type single crystal with Meyer’s index (n) of 2. The yield strength of the crystal was calculated. Dielectric constant and dielectric loss are measured as a function of frequency. The laser damage threshold of the TMP crystal was measured using an Nd: YAG laser with a wavelength of 1064 nm. Novelty: The various studies show that the TMP crystal possesses excellent optical properties and can be used for opto-electronics device fabrication.
