Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 428.40 g/mol gives Toltrazuril-D3 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Toltrazuril-D3 (CAS 1353867-75-0), molecular formula C18H11D3F3N3O4S and molecular weight 428.40 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to deuterium isotope labeling, a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, fluorine substitution, Toltrazuril-D3 is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 428.40 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
