FooDB Name(R)-2-Hydroxy-2H-1,4-benzoxazin-3(4H)-one
Description(R)-2-Hydroxy-2H-1,4-benzoxazin-3(4H)-one belongs to the class of organic compounds known as benzoxazinones. These are organic compounds containing a benzene fused to an oxazine ring (a six-member aliphatic ring with four carbon atoms, one oxygen atom, and one nitrogen atom) bearing a ketone group (R)-2-Hydroxy-2H-1,4-benzoxazin-3(4H)-one is an extremely weak basic (essentially neutral) compound (based on its pKa) (R)-2-Hydroxy-2H-1,4-benzoxazin-3(4H)-one has been detected, but not quantified in, several different foods, such as teffs, annual wild rices, red rices, rices, and wild rices. This could make (R)-2-hydroxy-2H-1,4-benzoxazin-3(4H)-one a potential biomarker for the consumption of these foods.
