Abstract
This study aims at synthesizing the compound of 4-(2',5'-dimetoksi phenyl)-3-buten-2-on and determining the character, physical properties, and yield of the synthesized compounds as well as the lowest concentration providing ultra protection. This research was initiated by reacting the compound of 2,5-dimetoksi benzaldehid with acetone. This synthesis used ethanol and aquades as solvents, and NaOH as the base catalyst. Synthesis reaction was carried out by stirring for 3 hours in an ice bath, followed by purification by recrystallization using solvents of ethanol and aquades. The synthesized compound was characterized by TLC, TLC Scanner, IR spectroscopy, UV, and 'H-NMR. Then, the synthesized compound’s potential as a sunscreen was tested. The results showed that the synthesized compound produced was not the compound of 4-(2',5'-dimetoksi phenyl)-3-buten-2-on, but the compound of 1,5 bis (2', 5'-dimetoksi phenyl)-1,4-pentadien-3-on with a yield of 54% and purity of 97.14%. The synthesized compound was crystal-shaped, yellow, and had a melting point of 102-104°C. The results of the potential test as a sunscreen showed that this compound had compound activity of UV-B sunscreens. The lowest concentration of 1,5-bis(2',5'-dimetoksi phenyl)-1,4-pentadien-3-on providing ultra protection was 30 ppm with an SPF value of 15.346.
