NMR-Lösungsmittel
NMR-Lösungsmittel sind spezialisierte Lösungsmittel, die in der Kernspinresonanzspektroskopie (NMR) verwendet werden, um Proben zu lösen, ohne die spektrale Analyse zu stören. Diese Lösungsmittel sind typischerweise deuteriert, um die eigenen NMR-Signale des Lösungsmittels zu minimieren und ein klares und genaues Spektrum des Analyten zu liefern. NMR-Lösungsmittel sind entscheidend für präzise chemische Verschiebungsmessungen und eine zuverlässige Dateninterpretation. Sie werden auch als analytische volumetrische Lösungen und Indikatoren verwendet, um die Kalibrierung und Validierung von NMR-Instrumenten zu erleichtern. Darüber hinaus unterstützen diese Lösungsmittel eine breite Palette von Anwendungen in der Forschung mit organischen chlorierten Verbindungen, unpolaren Lösungsmitteln und verschiedenen biochemischen Analysen. Ihre Rolle ist sowohl in der Forschung als auch in der Industrie unverzichtbar, da sie zur genauen Charakterisierung von Molekularstrukturen und -dynamiken beitragen.

Aspartame
CAS:Aspartame (SC-18862), an artificial, non-carbohydrate sweetener, is aspartyl-phenylalanine-1-methyl ester.Formel:C14H18N2O5Reinheit:98.92% - 99.27%Farbe und Form:Colorless Needles From Water SucroseMolekulargewicht:294.3Chloroform, Molecular Biology Reagent
CAS:Chloroform is a common laboratory reagent favored for use as a solvent due to the compounds relative unreactivity and miscibility with most organic compounds. Chloroform is also used in organic synthesis as a source for CCl2. In the swine tracheal smooth muscle, chloroform has been demonstrated to directly and in a concentration dependent manner induce contractions. It has been observed that Chloroform can release Ca2+ from ryanodine sensitive receptors in chloroform-induced contraction in swine tracheal smooth muscle. At concentrations of 100 and 250 ppm in mouse splenocyte, basal proliferation was increased yet a decrease in circulating neutrophils was documented.
