The occurrence of Aztreonam USP RC B(Open-ring Desulfated Aztreonam) is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
Aztreonam USP RC B(Open-ring Desulfated Aztreonam) (CAS 102586-36-7) is a high-purity analytical reference standard with the molecular formula C13H19N5O6S and a molecular weight of 373.38 g/mol.
The molecular framework of Aztreonam USP RC B(Open-ring Desulfated Aztreonam) (C13H19N5O6S) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage. 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. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
