Descrizione generale
meta-Phosphoric acid is a polymer form of phosphoric acid. It is used as a catalyst as well as a reactant in chemical synthesis.
Applicazioni
meta-Phosphoric acid can be used as:
- A catalyst in combination with InCl3 to synthesize 1,8-dioxooctahydroxanthene derivatives by the reaction of cyclic β-diketones and aldehydes.
- A phosphate precursor to synthesize antimony phosphate (SbPO4) by reacting with antimony metal at high temperatures.

Aging promotes accumulation of reactive oxygen/nitrogen species (ROS/RNS) in cardiomyocytes, which leads to contractile dysfunction and cardiac abnormalities. These changes may contribute to increased cardiovascular disease in the elderly. Inducible antioxidant pathways are regulated by nuclear erythroid 2 p45-related factor
