Description

CAS: 77-92-9 | C6H8O7 | 192.12 g/mol

Citric acid is a starting point in the Krebs cycle and is a key intermediate in metabolism. It has anticoagulant activity; as a calcium chelator, it forms complexes that disrupt the tendency of blood to clot. It may be used to adjust pH and as a sequestering agent for the removal of trace metals.

This Thermo Scientific Chemicals brand product was originally part of the Alfa Aesar product portfolio. Some documentation and label information may refer to the legacy brand. The original Alfa Aesar product / item code or SKU reference has not changed as a part of the brand transition to Thermo Scientific Chemicals.

Anwendungen
Zitronensäure ist ein Ausgangspunkt im Krebszyklus und ein wichtiges Zwischenprodukt im Stoffwechsel. Es hat eine antikoagulierende Wirkung; als Calcium-Chelator bildet es Komplexe, die die Tendenz des Blutes zur Gerinnung stören. Es kann zur Einstellung des pH-Wertes und als Komplexbildner zur Entfernung von Spurenmetallen verwendet werden.

Löslichkeit
Wasserlöslich. Auch in Alkohol und Methanol löslich. Nicht in Chloroform und Benzol löslich.

Hinweise
Hygroskopisch. Nicht kompatibel mit Oxidationsmitteln.
