Flavanones are compounds containing a flavan-3-one moiety, with a structure characterized by a 2-phenyl-3,4-dihydro-2H-1-benzopyran bearing a ketone at the carbon C3. Thus, butin is considered to be a flavonoid lipid molecule. Butin is practically insoluble (in water) and a very weakly acidic compound (based on its pKa). Butin can be found in mango, which makes butin a potential biomarker for the consumption of this food product. Butin may refer to: Butin is the mountain located in Pendro Butin (molecule), a flavanone Aleksandr Butin (born 1985), Russian professional football player Origny-le-Butin, a commune in the Orne department in northwestern France Butin, a village in Gătaia town, Timiş County, Romania . 7,3',4'-Trihydroxyflavanone C15H12O5 272.2528 272.068473494 (2S)-2-(3,4-dihydroxyphenyl)-7-hydroxy-3,4-dihydro-2H-1-benzopyran-4-one butin 492-14-8 OC1=CC2=C(C=C1)C(=O)C[C@H](O2)C1=CC=C(O)C(O)=C1 InChI=1S/C15H12O5/c16-9-2-3-10-12(18)7-14(20-15(10)6-9)8-1-4-11(17)13(19)5-8/h1-6,14,16-17,19H,7H2/t14-/m0/s1 MJBPUQUGJNAPAZ-AWEZNQCLSA-N belongs to the class of organic compounds known as flavanones.
