Heterocyclic compounds can be divided into two categories: alicyclic heterocycles and aromatic heterocycles. Compounds whose heterocycles in the molecular skeleton cannot reflect aromaticity are called alicyclic heterocyclic compounds. Compound: 13925-00-3, is researched, Molecular C6H8N2, about Characterization of the Key Aroma Compounds in Two Differently Dried Toona sinensis (A. Juss.) Roem. by Means of the Molecular Sensory Science Concept, the main research direction is aroma compound dried Toona leaf; aroma extract dilution analysis; aroma recombination; molecular sensory science concept; odor activity value; stable isotope dilution analysis.Application of 13925-00-3.
A systematic approach for the characterization of the key aroma-active compounds in sun-dried Toona sinensis (SDTS) and vacuum-dried T. sinensis (VDTS) was performed by means of the mol. sensory science concept. A total of 64 aroma-active compounds were identified via gas chromatog.-olfactometry (GC-O) and gas chromatog.-mass spectrometry (GC-MS). Aroma extract dilution anal. (AEDA) and static headspace dilution anal. revealed 39 odorants in SDTS and 32 odorants in VDTS with flavor dilution (FD) factors from 8 to 4096, with the highest for vanillin and eugenol in both samples. Stable isotope dilution anal. (SIDA) and an internal standard method were applied to quantitate 42 odorants, revealing 35 compounds in concentrations above their resp. odor thresholds in SDTS and 29 compounds in VDTS, resp. Calculation of odor activity values (OAVs) indicated 2-isopropyl-3-methoxypyrazine, eugenol, and β-ionone with the highest OAVs in both samples. Recombination experiments of the overall aromas of SDTS and VDTS by mixing the odorants with OAVs ≥1 in their naturally occurring concentrations proved the successful identification and quantitation of the resp. key odorants.
Different reactions of this compound(2-Ethylpyrazine)Application of 13925-00-3 require different conditions, so the reaction conditions are very important.
