Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
Tazobactam-XTE (CAS CATO-C4X-120523) is a high-purity analytical reference standard with the molecular formula C23H21BrN4O5S and a molecular weight of 545.41 g/mol.
Based on its molecular formula C23H21BrN4O5S, Tazobactam-XTE contains a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, bromine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 545.41 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
As a certified reference material (CRM), Tazobactam-XTE 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.
