A new method for the determination of sucrose in honey with derivatization solid-phase microextraction and gas chromatog./mass spectrometry (D-SPME-GC/MS) was developed. The method incorporates a sample derivatization with acetic anhydride using N-methylimidazole as the catalyst and the subsequent enrichment of the analyte in a Polyacrylate-SPME fiber. Results show that 100 μL N-methylimidazole and 800 μL acetic anhydride were sufficient to complete the acetylation for sucrose in 100 μL aqueous sample at room temperature For SPME, an enrichment time of 30 min was sufficient. SPME was performed by immersing the fiber into the solution with addnl. vibration. Then, the analyte was desorbed for 5 min at 280°C in the GC/MS injection port with splitless mode. The present method exhibits good linearity at a concentration range of 0.3-8% of sucrose in honey with excellent regression (R = 0.9993). The method has been successfully applied to the control of sucrose adulteration in honey. In the experiment, the researchers used many compounds, for example, (2R,3R,4S,5R,6R)-2-(Acetoxymethyl)-6-(((2S,3S,4R,5R)-3,4-diacetoxy-2,5-bis(acetoxymethyl)tetrahydrofuran-2-yl)oxy)tetrahydro-2H-pyran-3,4,5-triyl triacetate (cas: 126-14-7Computed Properties of C28H38O19).
(2R,3R,4S,5R,6R)-2-(Acetoxymethyl)-6-(((2S,3S,4R,5R)-3,4-diacetoxy-2,5-bis(acetoxymethyl)tetrahydrofuran-2-yl)oxy)tetrahydro-2H-pyran-3,4,5-triyl triacetate (cas: 126-14-7) belongs to tetrahydrofuran derivatives. THF (Tetrahydrofuran) is water-miscible and has a low viscosity making it a highly versatile solvent used in a variety of industries. Tetrahydrofuran reaction with hydrogen sulfide: In the presence of a solid acid catalyst, tetrahydrofuran reacts with hydrogen sulfide to give tetrahydrothiophene.Computed Properties of C28H38O19
