Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
Cyclosporin A-13C2,d4 Acetate (major) (CAS CATO-C4X-131110), molecular formula C62[13C]2H109D4N11O13 and molecular weight 1250.65 g/mol, is a CATO reference standard with documented purity and traceability.
Based on its molecular formula C62[13C]2H109D4N11O13, Cyclosporin A-13C2,d4 Acetate (major) contains deuterium isotope labeling, 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 1250.65 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).
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.
