Chemical Structure
Description
Rifambutin 21R Heterotropic Isomer (CAS CATO-C4X-25127) is a high-purity analytical reference standard with the molecular formula C46H62N4O11 and a molecular weight of 847.00 g/mol.
Based on its molecular formula C46H62N4O11, Rifambutin 21R Heterotropic Isomer contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 847.00 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).
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.
