CATO supplies 65501-24-8 EDTA tripotassium salt Edathamil Ethylenediaminetetraacetic acid tripotassium salt dihydrate MFCD00149672 Tripotassium ethylenediaminetetraacetate dihydrate (CAS 65501-24-8), a certified reference material (molecular formula C10H13N2O8KH2O, MW 346.33 g/mol) for analytical method development and quality control.
The molecular framework of 65501-24-8 EDTA tripotassium salt Edathamil Ethylenediaminetetraacetic acid tripotassium salt dihydrate MFCD00149672 Tripotassium ethylenediaminetetraacetate dihydrate (C10H13N2O8KH2O) is characterized by a carbohydrate-derived structure, an amide group. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
As a certified reference material (CRM), 65501-24-8 EDTA tripotassium salt Edathamil Ethylenediaminetetraacetic acid tripotassium salt dihydrate MFCD00149672 Tripotassium ethylenediaminetetraacetate 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.
