Egta is a documented reagent, chemically identified as a compound with the molecular formula C10H13NO2 and a molecular weight of 179.22. It exhibits a Melting Point range of 133.9 to 137.8°C and decomposes at temperatures near its normal Boiling Point. This compound carries a danger signal word due to its potential harmfulness if ingested. Egta serves as a potent unspecific protease inhibitor, primarily through the chelation of calcium and magnesium ions, thereby removing them from the surrounding medium. Its affinity towards calcium 2+ is significantly stronger compared to magnesium 2+. The inhibitory effect can be countered by an excess of either calcium or magnesium ions.
