Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 421.66 g/mol gives Diclazuril-methyl distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies Diclazuril-methyl (CAS 103337-71-9), a certified reference material (molecular formula C18H11Cl3N4O2, MW 421.66 g/mol) for analytical method development and quality control.
Diclazuril-methyl (C18H11Cl3N4O2) contains a steroid core, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
As a certified reference material (CRM), Diclazuril-methyl 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.
