CAS 7291-22-7
:Pyridine-d5
Description:
Pyridine-d5, with the CAS number 7291-22-7, is a deuterated form of pyridine, a heterocyclic aromatic organic compound. It is characterized by a six-membered ring containing five carbon atoms and one nitrogen atom, where five hydrogen atoms are replaced by deuterium, a stable isotope of hydrogen. This substitution enhances its utility in nuclear magnetic resonance (NMR) spectroscopy, as it provides a distinct spectral signature due to the presence of deuterium. Pyridine-d5 is a colorless liquid with a characteristic odor, similar to that of regular pyridine, and is miscible with water and organic solvents. It is commonly used as a solvent and reagent in various chemical reactions, particularly in studies involving isotopic labeling. The presence of the nitrogen atom contributes to its basicity and reactivity, making it a valuable compound in organic synthesis and analytical chemistry. Safety precautions should be observed when handling this compound, as it can be toxic and irritating to the skin and respiratory system.

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:C5D5NPurity:Min. 95%Molecular weight:254.37 g/molPyridine-d5 For NMR Spectroscopy, 99.5 Atom %D
