Edetate Disodium Dihydrogen, Dihydrate, Primary Standard is a single component organic chemical reference standard. Reference standards are particularly important for analytical chemistry since most analytical instrumentation is comparative; it requires a sample of known composition (reference standard) for accurate calibration. These reference standards are produced under stringent manufacturing procedures and differ from laboratory reagents in their certification and the traceability of the data provided.
