Di-O-acetyl-L-tartaric anhydride - 96%, high purity , CAS No.6283-74-5
Basic Description Synonyms 6283-74-5 | (+)-Diacetyl-L-tartaric anhydride | (3R,4R)-2,5-Dioxotetrahydrofuran-3,4-diyl diacetate | Di-O-acetyl-L-tartaric Anhydride | 2,5-Furandione, 3,4-bis(acetyloxy)dihydro-, (3R,4R)- | L-diacetyltartaric anhydride | D7XNF76O0K | diacetyltartaric acid anhydride | [ Specifications & Purity ≥96% Storage Temp Store at 2-8°C,Argon charged Shipped In Wet ice Product Description (+)-O,O′-Diacetyl-L-tartaric anhydride is an HPLC derivatization reagent for UV/Vis detection. It is mainly employed as a reagent for the chiral derivatization of amino alcohols. It also reacts with alkanoamines in aprotic medium containing trichloroacetic acid and produces tartaric acid monoesters
(+)-O,O′-Diacetyl-L-tartaric anhydride may be used as a chiral derivatizating agent in the following:
• determination of enantiomeric vigabatrin in mouse serum samples using ultra-high performance liquid chromatography-quadrupole-time-of-flight mass spectrometry (UHPLC-Q-TOF-M)
• determination of trantinterol in rat plasma by ultra performance liquid chromatography–electrospray ionization mass spectrometry (UPLC–MS/MS)
