Application In Synthesis of 3-Methyl-1H-pyrrole. The mechanism of aromatic electrophilic substitution of aromatic heterocycles is consistent with that of benzene. Compound: 3-Methyl-1H-pyrrole, is researched, Molecular C5H7N, CAS is 616-43-3, about Sensory and Instrumental Analyses of Volatiles Generated during the Extrusion Cooking of Oat Flours. Author is Parker, Jane K.; Hassell, Glynis M. E.; Mottram, Donald S.; Guy, Robin C. E..
Three batches of oats were extruded under four combinations of process temperature (150 or 180°C) and process moisture (14.5 and 18%). Two of the extrudates were evaluated by a sensory panel, and three were analyzed by GC-MS. Maillard reaction products, such as pyrazines, pyrroles, furans, and sulfur-containing compounds, were found in the most severely processed extrudates (high-temperature, low-moisture). These extrudates were also described by the assessors as having toasted cereal attributes. Lipid degradation products, such as alkanals, 2-alkenals, and 2,4-alkadienals, were found at much higher levels in the extrudates of the oat flour that had been debranned. It contained lower protein and fiber levels than the others and showed increased lipase activity. Extrudates from these samples also had significantly lower levels of Maillard reaction products that correlated, in the sensory anal., with terms such as stale oil and oatmeal. Linoleic acid was added to a fourth oat flour to simulate the result of increased lipase activity, and GC-MS anal. showed both an increase in lipid degradation products and a decrease in Maillard reaction products.
After consulting a lot of data, we found that this compound(616-43-3)Application In Synthesis of 3-Methyl-1H-pyrrole can be used in many types of reactions. And in most cases, this compound has more advantages.
