Chemical Structure
Description
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.
Cyproterone Acetate-D3 (CAS 427-51-0 (non-labelled)), molecular formula C24H26D3ClO4 and molecular weight 419.96 g/mol, is a CATO reference standard with documented purity and traceability.
Based on its molecular formula C24H26D3ClO4, Cyproterone Acetate-D3 contains deuterium isotope labeling, a flavonoid core, a hydroxyl group, an ether linkage, chlorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 419.96 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.
