Description
As a certified reference material (CRM), TSPP (tetrasodium) 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.
CATO supplies TSPP (tetrasodium) (CAS 39050-26-5), a certified reference material (molecular formula C44H26N4Na4O12S4, MW 1022.92 g/mol) for analytical method development and quality control.
Based on its molecular formula C44H26N4Na4O12S4, TSPP (tetrasodium) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 1022.92 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
