CAS 7291-22-7: Piridina-d5
Descrizione:
Piridina-d5, con il numero CAS 7291-22-7, è una forma deuterata della piridina, un composto organico aromatico eterociclico. È caratterizzato da un anello a sei membri contenente cinque atomi di carbonio e un atomo di azoto, dove cinque atomi di idrogeno sono sostituiti da deuterio, un isotopo stabile dell'idrogeno. Questa sostituzione ne migliora l'utilità nella spettroscopia di risonanza magnetica nucleare (NMR), poiché fornisce una firma spettrale distinta grazie alla presenza di deuterio. Piridina-d5 è un liquido incolore con un odore caratteristico, simile a quello della piridina normale, ed è miscibile con acqua e solventi organici. Viene comunemente utilizzato come solvente e reagente in varie reazioni chimiche, in particolare in studi che coinvolgono l'etichettatura isotopica. La presenza dell'atomo di azoto contribuisce alla sua basicità e reattività, rendendolo un composto prezioso nella sintesi organica e nella chimica analitica. Devono essere osservate precauzioni di sicurezza quando si maneggia questo composto, poiché può essere tossico e irritante per la pelle e il sistema respiratorio.

CAS:Prodotto controllatoApplications 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.Formula:C5D5NPurezza:Min. 95%Peso molecolare:254.37 g/molPyridine-D5 >99.50 Atom % D 25ml Bottle
