Dodeca-2E,4E,8Z,10E,Z-tetraensäureisobutylamid
Dodeca-2E,4E,8Z,10E,Z-tetraensäureisobutylamid - Referenzsubstanz liegt als Isomerenmischung (10E und 10Z) vor, daher basiert der Absolutgehalt auf quantitativer NMR. Die Isomere unterscheiden sich in der UV-Absorption, sind in der HPLC schlecht aufgelöst, Peakflächen differieren. Chargen weisen ggf. unterschiedliche Isomerenzusammensetzungen auf, daher kann die Kontinuität der Gehaltswerte bei Chargenwechsel mittels HPLC-UV nicht belegt werden. Selbst bei identischen Absolutgehalten weichen die Peakflächen ggf. signifikant ab. Eine zusätzliche Unschärfe kommt hinzu, wenn das Isomerenverhältnis der Probe von dem des Standards abweicht. Daher empfehlen wir diesen Referenzstandard ausschließlich für qualitative Zwecke einzusetzen und sich die analytischen Herausforderungen bewusst zu machen. Dennoch zertifizieren wir die Ergebnisse der quantitativen Prüfungen und einen Absolutgehalt. Detaillierte Informationen auf den Begleitdokumenten.
Aus Stabilitätsgründen wurde die Referenzsubstanz Dodeca-2E,4E,8Z,10E,Z-tetraensäureisobutylamid in Acetonitril gelöst und ist nur in Einheiten á 10 mg in ca. 1 ml Acetonitril erhältlich. Die Rabattstaffel für größere Einheiten ist für diesen Referenzstandard daher nicht anwendbar. Es handelt sich um ein Gemisch der 10E- und 10Z-Isomere.

Dodeca 2E,4E,8Z,10E,Z-ácido Z-tetraenoico isobutilomida la sustancia de referencia es un estándar de referencia primario con pureza absoluta certificada (considerando la pureza cromatográfica, agua, solventes residuales, impurezas inorgánicas).
Por razones de estabilidad, esta sustancia de referencia de ácido dodeca 2E,4E,8Z,10E,Z-tetraenoico isobutilamida ha sido disuelta en acetonitrilo y está disponible en porciones de 10 mg en aproximadamente 1 mL de acetonitrilo solamente.Por lo tanto, el esquema de descuento para unidades más grandes no es aplicable a este estándar de referencia. Esta sustancia de referencia es una mezcla de los isómeros 10E y 10Z.
The substance is a mixture of two isomers, 10E and 10Z, which show differences in UV absorbance, and thus also the peak areas of both isomers differ in HPLC. Furthermore, different batches may vary in their composition of the isomers, which are usually also only poorly resolved by HPLC. A comparison between peak areas of different batches is, therefore, impossible, and batch to batch continuity cannot be proven by HPLC-UV. Keep in mind that - even if the certified absolute purity of different batches is identical, or taken into account in the quantitative calculations - the peak areas obtained in HPLC analysis can differ significantly. Additional uncertainty is introduced if the isomer distribution in the analyzed sample differs from the isomer ratio in this reference substance. For these reasons we strongly recommend to use the reference substance for qualitative purposes only. Please refer to the COA for more details. Packed under nitrogen. Recommended to be stored under inert atmosphere. Avoid exposure to oxygen.
The compound has been dissolved in approx. 1 mL of acetonitrile. The exact weight is given on the label of the vial. In order to produce a stock solution of known concentration please transfer the contents of the vial quantitatively into a volumetric flask by repeated rinsing with excess solvent and then fill to the mark.
