Abstract

Synthesis of the compound n-(hydroxyphenyl)-3,4-dimethoxybenzamide through the amidation reaction of 3,4-dimethoxybenzaldehyde with p-aminophenol has been carried out. The purpose of this study was to synthesize and characterize p-aminophenol derivatives using 3,4-dimethoxybenzaldehyde and to determine the characteristics of n-(hydroxyphenyl)-3,4-dimethoxybenzamide using IR spectrophotometer, UV-vis spectroscopy and mass spectroscopy. The compound n-(hydroxyphenyl)-3,4-dimethoxybenzamide was synthesized through an amidation reaction between an aldehyde compound in the form of 3,4- dimethoxybenzaldehyde and an amine in the form of p-aminophenol. The synthesized product was identified by melting point, IR spectrophotometer, UV-Vis spectroscopy and mass spectroscopy. The results of the study were chocolate crystals with a melting point of 163°C and a percentage yield of 43%. The results of the characterization of the compound N-(hydroxyphenyl)-3,4-dimethoxybenzamide using the UV-Vis instrument resulted in an absorption peak of wavelength (α) 236 nm. The results of FTIR identification resulted in a vibrational absorption of the carbonyl group (-C=O) on the amide in the absorption region of 1620 cm-1, strengthened by absorption in the area of 3340 cm-1 and 3278 cm-1, there was a double amide peak indicating the presence of a -NH group. MS identification results showed the molecular weight of the product was 109.13 g/mol.
