Pyrrole
Pyrrole is found in corn. Pyrrole is a flavouring ingredient Pyrrole has very low basicity compared to conventional amines and some other aromatic compounds like pyridine. This decreased basicity is attributed to the delocalization of the lone pair of electrons of the nitrogen atom in the aromatic ring. Pyrrole is a very weak base with a pKaH of about 4. Protonation results in loss of aromaticity, and is, therefore, unfavorable. Pyrrole is a heterocyclic aromatic organic compound, a five-membered ring with the formula C4H4NH. Substituted derivatives are also called pyrroles. For example, C4H4NCH3 is N-methylpyrrole. Porphobilinogen is a trisubstituted pyrrole, which is the biosynthetic precursor to many natural products. The starting materials in the Piloty-Robinson pyrrole synthesis are 2 equivalents of an aldehyde and hydrazine. The product is a pyrrole with specific substituents in the 3 and 4 positions. The aldehyde reacts with the diamine to an intermediate di-imine (R C=N N=C R), which, with added hydrochloric acid, gives ring-closure and loss of ammonia to the pyrrole CONFIDENCE standard compound; INTERNAL_ID 8155 Flavouring ingredient
2-Furanmethanol
2-Furanmethanol, also known as 2-furylcarbinol or furfural alcohol, belongs to the class of organic compounds known as heteroaromatic compounds. Heteroaromatic compounds are compounds containing an aromatic ring where a carbon atom is linked to an hetero atom. Its structure is that of a furan bearing a hydroxymethyl substituent at the 2-position. 2-Furanmethanol is a sweet, alcoholic and bitter tasting compound. 2-Furanmethanol has been detected, but not quantified, in several different foods, such as cereals and cereal products, potato, white mustards, arabica coffee, and cocoa and cocoa products. This could make 2-furanmethanol a potential biomarker for the consumption of these foods.

2-Pentylfuran
2-pentylfuran is a member of the class of compounds known as heteroaromatic compounds. Heteroaromatic compounds are compounds containing an aromatic ring where a carbon atom is linked to an hetero atom. 2-pentylfuran is practically insoluble (in water) and an extremely weak basic (essentially neutral) compound (based on its pKa). 2-pentylfuran is a beany, butter, and earthy tasting compound and can be found in a number of food items such as yellow bell pepper, pepper (c. annuum), nuts, and watermelon, which makes 2-pentylfuran a potential biomarker for the consumption of these food products. 2-pentylfuran can be found primarily in feces, saliva, and urine. 2-pentylfuran exists in all eukaryotes, ranging from yeast to humans. 2-pentylfuran is a colourless to light yellow liquid that is not known to be produced by mammalian metabolism. It is present in many foods including alcoholic beverages, coffee, potatoes, tomatoes, roasted filberts, and soybean oil, and it is also a component of the aroma of these foods. 2-pentylfuran is a flavouring ingredient. 2-pentylfuran belongs to the furan family which is characterized by a furan ring (a five-member aromatic ring with one oxygen atom and four carbon atoms). A study showed that 2-pentylfuran is found in the breath of patients with Aspergillus fumigatus infections (PMID:19301177). 2-pentylfuran is a member of the class of furans that is furan in which the hydrogen at position 2 is replaced by a pentyl group. It is found in many heat-processed foods and drinks. It has a role as an Aspergillus metabolite, a human urinary metabolite, a volatile oil component, an insect repellent, a flavouring agent, a plant growth stimulator and a bacterial metabolite. 2-Pentylfuran is a natural product found in Vitis rotundifolia, Astragalus mongholicus, and other organisms with data available. 2-pentylfuran is a metabolite found in or produced by Saccharomyces cerevisiae. A member of the class of furans that is furan in which the hydrogen at position 2 is replaced by a pentyl group. It is found in many heat-processed foods and drinks. 2-Pentylfuran is the compound isolated from steam volatile oils obtained from potatoes at atmospheric pressure[1]. 2-Pentylfuran is the compound isolated from steam volatile oils obtained from potatoes at atmospheric pressure[1].

2-Pentylthiophene
2-Pentylthiophene is a member of thiophenes. 2-Pentylthiophene belongs to the class of organic compounds known as heteroaromatic compounds. Heteroaromatic compounds are compounds containing an aromatic ring where a carbon atom is linked to an hetero atom. 2-Pentylthiophene is possibly neutral. 2-Pentylthiophene is a sweet, cranberry, and fatty tasting compound. 2-Pentylthiophene has been detected, but not quantified, in herbs and spices and mushrooms. 2-Pentylthiophene has been found to be associated with several diseases such as pervasive developmental disorder not otherwise specified and autism in humans. 2-pentylthiophene has also been linked to the inborn metabolic disorder celiac disease.

2,5-Dimethylfuran
2,5-Dimethylfuran is a derivative of furan. It is a heterocyclic compound of the formula C6H8O. While it may be abbreviated DMF, it should not be confused with dimethylformamide. 2,5-Dimethylfuran is a maillard product. 2,5-Dimethylfuran has been identified as one of the components of cigar smoke with low cilatoxicity (ability to adversely affect the cilia in the respiratory tract that are responsible for removing foreign particles). Its blood concentration can be used as a biomarker for smoking. 2,5-Dimethylfuran, together with 2,5-hexanedione and 4,5-dihydroxy-2-hexanone, is one of the main metabolites of hexane in humans, which play a role in the mechanism for the neurotoxicity of hexane.Recent advances have increased its attractiveness as a biofuel. Maillard product
3-Methylthiophene
3-Methylthiophene is found in coffee and coffee products. 3-Methylthiophene is a maillard product, present in roast coffee aroma. Maillard product, present in roast coffee aroma. 3-Methylthiophene is found in coffee and coffee products and guava. D001697 - Biomedical and Dental Materials
Thiophene
Thiophene is a maillard product. At room temperature, thiophene is a colorless liquid with a mildly pleasant odor reminiscent of benzene, with which thiophene shares some similarities. The high reactivity of thiophene toward sulfonation is the basis for the separation of thiophene from benzene, which are difficult to separate by distillation due to their similar boiling points (4 °C difference at ambient pressure). Like benzene, thiophene forms an azeotrope with water. Not only is thiophene reactive toward electrophiles, it is also readily lithiated with butyl lithium to give 2-lithiothiophene, which is a precursor to a variety of derivatives, including dithienyl Maillard product
