Chemical Structure
Description
Structurally, Rifabutin-d7 (C46H55D7N4O11) contains deuterium isotope labeling, a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 21.5, corresponding to approximately 21 ring(s) or double-bond equivalent(s). With a molecular weight of 854.06 g/mol, it falls into the high-molecular-weight range. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
Rifabutin-d7 (CAS CATO-C4X-25121), molecular formula C46H55D7N4O11 and molecular weight 854.06 g/mol, is a CATO reference standard with documented purity and traceability.
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.
