CAS 7291-22-7: Pyridin-d5
Beschreibung:
Pyridin-d5, mit der CAS-Nummer 7291-22-7, ist eine deuterierte Form von Pyridin, einer heterocyclischen aromatischen organischen Verbindung. Es ist durch einen sechsgliedrigen Ring gekennzeichnet, der fünf Kohlenstoffatome und ein Stickstoffatom enthält, wobei fünf Wasserstoffatome durch Deuterium, ein stabiles Isotop von Wasserstoff, ersetzt sind. Diese Substitution erhöht seine Nützlichkeit in der Kernspinresonanzspektroskopie (NMR), da sie aufgrund der Anwesenheit von Deuterium ein unverwechselbares Spektralsignal liefert. Pyridin-d5 ist eine farblose Flüssigkeit mit einem charakteristischen Geruch, ähnlich dem von normalem Pyridin, und ist mit Wasser und organischen Lösungsmitteln mischbar. Es wird häufig als Lösungsmittel und Reagenz in verschiedenen chemischen Reaktionen verwendet, insbesondere in Studien, die isotopisches Labeling betreffen. Die Anwesenheit des Stickstoffatoms trägt zu seiner Basizität und Reaktivität bei, was es zu einer wertvollen Verbindung in der organischen Synthese und analytischen Chemie macht. Sicherheitsvorkehrungen sollten beim Umgang mit dieser Verbindung beachtet werden, da sie giftig und reizend für die Haut und das Atmungssystem sein kann.

CAS:Kontrolliertes ProduktApplications Pyridine-d5 is the labeled analogue of Pyridine (P991280), a basic six-membered heterocyclic ring. Pyridine is a base structure present in many biologically active compounds like the vitamins niacin and pyridoxal. Pyridine is used in dehalogenation reactions and can be used as a base in condensation reactions.

CAS:Stevioside is a high-purity steviol glycoside that is used in the food and pharmaceutical industries. Stevioside has been shown to have a variety of health benefits, including antioxidant, antimicrobial, and anti-inflammatory activities. It also has been shown to inhibit the growth of certain bacteria and fungi. This compound is an N-oxide with a hydroxyl group at carbon 12b. The reaction mechanism for this compound involves the formation of intramolecular hydrogen bonds between the hydroxyl group at carbon 12b and an oxygen atom from another molecule of stevioside. These intramolecular hydrogen bonds produce fluorescence when exposed to ultraviolet light (UV). Stevioside also has conformational properties that depend on its chirality; it exists as two enantiomers: D-stevioside and L-stevioside.Formel:C5D5NReinheit:Min. 95%Molekulargewicht:254.37 g/molPyridine-D5 >99.50 Atom % D 25ml Bottle
