Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 230.10 g/mol gives Trisodium Citrate Dihydrate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Trisodium Citrate Dihydrate (CAS 6132-04-3), molecular formula C6H5O7NaH2O and molecular weight 230.10 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of Trisodium Citrate Dihydrate (C6H5O7NaH2O) is characterized by a carbohydrate-derived structure. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
As a certified reference material (CRM), Trisodium Citrate Dihydrate meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
