Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 580.58 g/mol gives Setomimycin distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Setomimycin (CAS 69431-87-4), molecular formula C34H28O9 and molecular weight 580.58 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, Setomimycin (C34H28O9) contains a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system. The molecule exhibits a degree of unsaturation (DBE) of 21.0, corresponding to approximately 21 ring(s) or double-bond equivalent(s). With a molecular weight of 580.58 g/mol, it falls into the moderately-high-molecular-weight range. 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.
