Anwendungen

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.

Bemerkungen

Hygroscopic. Incompatible with oxidizing agents.
