CAS 7291-22-7: Pyridine-d5
Description :
Pyridine-d5, avec le numéro CAS 7291-22-7, est une forme deutérée de la pyridine, un composé organique aromatique hétérocyclique. Il se caractérise par un cycle à six membres contenant cinq atomes de carbone et un atome d'azote, où cinq atomes d'hydrogène sont remplacés par du deutérium, un isotope stable de l'hydrogène. Cette substitution améliore son utilité en spectroscopie par résonance magnétique nucléaire (RMN), car elle fournit une signature spectrale distincte en raison de la présence de deutérium. Pyridine-d5 est un liquide incolore avec une odeur caractéristique, similaire à celle de la pyridine ordinaire, et est miscible avec l'eau et les solvants organiques. Il est couramment utilisé comme solvant et réactif dans diverses réactions chimiques, en particulier dans les études impliquant le marquage isotopique. La présence de l'atome d'azote contribue à sa basicité et à sa réactivité, ce qui en fait un composé précieux en synthèse organique et en chimie analytique. Des précautions de sécurité doivent être observées lors de la manipulation de ce composé, car il peut être toxique et irritant pour la peau et le système respiratoire.

CAS :Produit contrôléApplications 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.Formule :C5D5NDegré de pureté :Min. 95%Masse moléculaire :254.37 g/molPyridine-D5 >99.50 Atom % D 25ml Bottle
