Common Name

1-hydroxy-3-(phenylmethylidene)-6h,7h,8h,8ah-pyrrolo[1,2-a]pyrazin-4-one

Description

AC1LDG67 belongs to the class of organic compounds known as alpha amino acids and derivatives. These are amino acids in which the amino group is attached to the carbon atom immediately adjacent to the carboxylate group (alpha carbon), or a derivative thereof. 1-hydroxy-3-(phenylmethylidene)-6h,7h,8h,8ah-pyrrolo[1,2-a]pyrazin-4-one is found in Garcinia atroviridis. AC1LDG67 is an extremely weak basic (essentially neutral) compound (based on its pKa).
