용도

2,3-Butanedione is used to form triazine and pteridine ring systems by cyclocondensation with amines. It is also used to inactivate aminopeptidase-N and acts as a precursor to alpha-diones. It finds use in alcoholic beverages, foods, to modify arginyl residues in proteins and to give a buttery flavor to microwave popcorns.

참고

Store in a cool place. Incompatible with acids, strong bases, metals, reducing agents and oxidizing agents.

Like 1,2-Cyclohexanedione, A14401, has been used by Ley's group in combination with trimethyl orthoformate and camphorsulfonic acid for the protection of trans-1,2-diols as cyclic diacetals. The method is particularly applicable to the carbohydrate field: Synlett, 793 (1996); J. Chem. Soc., Perkin 1, 2023 (1997). See also 9,10-Phenanthrenequinone, A11762.
