Diethyl succinate-13C4

Diethyl succinate-13C4 is the 13C labeled Diethyl succinate[1]. Diethyl succinate (Diethyl Butanedioate) is used at physiological pH and crosses biological membranes, incorporates into cells in tissue culture and is metabolized by the TCA cycle. Diethyl succinate is known to be non-toxic and used in fragrances and flavoring[2].
