Piperidine

Piperidine ON rasta resin

C5H11N (85.0891)


Piperidine (Azinane after the Hantzsch Widman nomenclature) is an organic compound with the molecular formula (CH2)5NH. This heterocyclic amine consists of a six-membered ring containing five methylene units and one nitrogen atom. It is a colorless fuming liquid with an odor described as ammoniacal, pepper-like; the name comes from the genus name Piper, which is the Latin word for pepper. Piperidine is found in barley, black pepper (Piper nigrum). Piperidine has been found to be a microbial metabolite. Piperidine is a flavouring agent and it is also widely used as a building block and chemical reagent in the synthesis of organic compounds, including pharmaceuticals. Piperidine is a widely used secondary amine. It is used to convert ketones to enamines. Enamines derived from piperidine can be used in the Stork enamine alkylation reaction. Piperidine is used as a solvent and as a base. The same is true for certain derivatives: N-formylpiperidine is a polar aprotic solvent with better hydrocarbon solubility than other amide solvents, and 2,2,6,6-tetramethylpiperidine is highly sterically hindered base, useful because of its low nucleophilicity and high solubility in organic solvents.

Acetone cyanohydrin

2-Hydroxy-2-methylpropanenitrile

C4H7NO (85.0528)


Acetone cyanohydrin, also known as 2-hydroxyisobutyronitrile or 2-methyllactonitrile, is a member of the class of compounds known as tertiary alcohols. Tertiary alcohols are compounds in which a hydroxy group, -OH, is attached to a saturated carbon atom R3COH (R not H ). Acetone cyanohydrin is soluble (in water) and a very weakly acidic compound (based on its pKa). Acetone cyanohydrin can be found in a number of food items such as burdock, sweet marjoram, rice, and garland chrysanthemum, which makes acetone cyanohydrin a potential biomarker for the consumption of these food products. Acetone cyanohydrin is a non-carcinogenic (not listed by IARC) potentially toxic compound. Acetone cyanohydrin (ACH) is an organic compound used in the production of methyl methacrylate, the monomer of the transparent plastic polymethyl methacrylate (PMMA), also known as acrylic.

2-Pyrrolidinone

pyrrolidin-2-one

C4H7NO (85.0528)


2-Pyrrolidinone is a lactam cyclization product of gamma-aminobutyric acid (GABA) (PMID 10332870). Vigabatrin (VGB, an antiepileptic drug) increases human brain gamma-aminobutyric acid (GABA) and the related metabolites, including 2-pyrrolidinone. Patients taking VGB are expected to have an increase of these metabolites (PMID 10403220, 10840398). 2-Pyrrolidone is an organic compound consisting of a five-membered lactam. It is a colorless liquid which is used in industrial settings as a high-boiling non-corrosive polar solvent for a wide variety of applications. It is miscible with a wide variety of other solvents including water, ethanol, diethyl ether, chloroform, benzene, ethyl acetate and carbon disulfide. Pyrrolidin-2-one is the simplest member of the class of pyrrolidin-2-ones, consisting of pyrrolidine in which the hydrogens at position 2 are replaced by an oxo group. The lactam arising by the formal intramolecular condensation of the amino and carboxy groups of gamma-aminobutyric acid (GABA). It has a role as a polar solvent and a metabolite. 2-Pyrrolidinone is a natural product found in Ascochyta medicaginicola, Microtropis japonica, and other organisms with data available. The simplest member of the class of pyrrolidin-2-ones, consisting of pyrrolidine in which the hydrogens at position 2 are replaced by an oxo group. The lactam arising by the formal intramolecular condensation of the amino and carboxy groups of gamma-aminobutyric acid (GABA). Present in red ginseng 2-Pyrrolidone. CAS Common Chemistry.

Thiazole

Photinus luciferin

C3H3NS (84.9986)


Thiazole is a flavouring ingredient The thiazole moiety is a crucial part of vitamin B1 (thiamine) and epothilone. Other important thiazoles are benzothiazoles, for example, the firefly chemical luciferin. Thiazole, or 1,3-thiazole, is a clear to pale yellow flammable liquid with a pyridine-like odor and the molecular formula C3H3NS. It is a 5-membered ring, in which two of the vertices of the ring are nitrogen and sulfur, and the other three are carbons. Thiazoles are a class of organic compounds related to azoles with a common thiazole functional group. Thiazoles are aromatic Flavouring ingredient
