Chemical Structure
Description
Toltrazuril sulfoxide-D3 (CAS 1346603-43-7), molecular formula C18H11D3F3N3O5S and molecular weight 444.40 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of Toltrazuril sulfoxide-D3 (C18H11D3F3N3O5S) is characterized by deuterium isotope labeling, a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, fluorine substitution. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
As a certified reference material (CRM), Toltrazuril sulfoxide-D3 meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
