Abstract: Complex formation between dopamine hydrochloride and vanillin using a colorimetric method was investigated to develop a simple and effective approach for the detection and quantification of dopamine. Dopamine, a neurotransmitter with significant biological importance, reacts with vanillin, an aromatic aldehyde in ethanol, resulting in a color change (colorless to light brown) that was measured using colorimetry. The optimal conditions for complex formation with a specific molar ratio of dopamine hydrochloride to vanillin have been studied to establish a calibration curve correlating absorbance with dopamine hydrochloride concentration, allowing for the accurate quantification of dopamine hydrochloride. This colorimetric method provides a cost-effective, accessible, and reliable means of detecting dopamine, with potential applications in clinical diagnostics, pharmaceutical analysis, and neurological research. The above method offers a quantitative way to determine up to 4 ppm levels of dopamine hydrochloride.
