Piridina-d5

Descrição:

Piridina-d5, com o número CAS 7291-22-7, é uma forma deuterada da piridina, um composto orgânico aromático heterocíclico. É caracterizado por um anel de seis membros contendo cinco átomos de carbono e um átomo de nitrogênio, onde cinco átomos de hidrogênio são substituídos por deuterio, um isótopo estável do hidrogênio. Essa substituição aumenta sua utilidade na espectroscopia de ressonância magnética nuclear (RMN), pois fornece uma assinatura espectral distinta devido à presença de deuterio. Piridina-d5 é um líquido incolor com um odor característico, semelhante ao da piridina comum, e é miscível com água e solventes orgânicos. É comumente usado como solvente e reagente em várias reações químicas, particularmente em estudos envolvendo rotulagem isotópica. A presença do átomo de nitrogênio contribui para sua basicidade e reatividade, tornando-o um composto valioso na síntese orgânica e na química analítica. Devem ser observadas precauções de segurança ao manusear este composto, pois pode ser tóxico e irritante para a pele e o sistema respiratório.

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.
