Most of the compounds have physiologically active properties, and their biological properties are often attributed to the heteroatoms contained in their molecules, and most of these heteroatoms also appear in cyclic structures. A Journal, Article, Chemistry & Biodiversity called Synthesis and in vitro antimicrobial activity screening of new 3-acetyl-2,5-disubstituted-1,3,4-oxadiazoline derivatives, Author is Popiolek, Lukasz; Biernasiuk, Anna; Paruch, Kinga; Malm, Anna; Wujec, Monika, which mentions a compound: 2689-65-8, SMILESS is IC1=CC=C(O1)C=O, Molecular C5H3IO2, Formula: C5H3IO2.
Thirteen new 3-acetyl-2,5-disubstituted-1,3,4-oxadiazoline derivatives were synthesized from corresponding hydrazide-hydrazones of isonicotinic acid in the reaction with acetic anhydride. The obtained compounds were identified with the use of spectral methods (IR, 1H-NMR, 13C-NMR, MS). In vitro antimicrobial activity screening of synthesized compounds against a panel of bacteria and fungi revealed interesting antibacterial and antifungal activity of tested 1,3,4-oxadiazoline derivatives, which is comparable to that of commonly used antimicrobial agents.
In some applications, this compound(2689-65-8)Formula: C5H3IO2 is unique.If you want to know more details about this compound, you can contact with the author or consult more relevant literature.
