Chemical Structure
Description
Owing to a carbohydrate-derived structure, an amide group, Tetrasodium Ethylenediaminetetraacetate Tetrahydrate is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 329.22 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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).
CATO supplies Tetrasodium Ethylenediaminetetraacetate Tetrahydrate (CAS 13235-36-4), a certified reference material (molecular formula C10H12N2O8NaH2O, MW 329.22 g/mol) for analytical method development and quality control.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
As a certified reference material (CRM), Tetrasodium Ethylenediaminetetraacetate Tetrahydrate 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.
