Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
Ethylenediaminetetraacetic Acid Lead(II) Disodium Salt Hydrate (CAS 21135-97-7), molecular formula C10H12N2O8Pb and molecular weight 495.41 g/mol, is a CATO reference standard with documented purity and traceability.
Ethylenediaminetetraacetic Acid Lead(II) Disodium Salt Hydrate (C10H12N2O8Pb) contains a carbohydrate-derived structure, an amide group. It is notably hygroscopic, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
CATO manufactures Ethylenediaminetetraacetic Acid Lead(II) Disodium Salt Hydrate under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
