Analysing the synthesis and characterization of semi-organic compound tartaric acid ammonium chloride by slow evaporation method

Single crystal synthesis, growth and characterization pose challenges such as impurities, temperature control issues and mechanical stress. The present study aims to address these issues by synthesizing and exploring the physico-chemical properties of a nonlinear semi-organic crystal, tartaric acid and ammonium chloride (TAAC). The crystal growth occurred via the slow evaporation method at ambient temperature using double-deionized water as a solvent. Physico-chemical properties were tested, and characterization included X-ray diffraction, scanning electron microscopy (SEM), and photoluminescence to analyse structure, purity and morphology. Additionally, Fourier-transform infrared spectroscopy, UV-visible spectra and micro hardness methods were employed to analyse the optical properties and determine band-gap energy. Antifungal and antibacterial activities against Candida albicans, Staphylococcus aureus and Pseudomonas aeruginosa were evaluated using the agar-well diffusion method. TAAC demonstrated superior structure and characteristics compared to potassium dihydrogen phosphate crystals across all parameters.
