Description
Methyl 6-[(E)-2-{2-[3-chloro-5-(trifluoromethyl)pyridin-2-yl]-2-methylhydrazin-1-yl}ethenyl]-2-oxo-3-[3-(trifluoromethyl)benzamido]-2H-pyran-5-carboxylate (CAS 341966-28-7), molecular formula C24H17ClF6N4O5 and molecular weight 590.86 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a flavonoid core, an amide group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution, Methyl 6-[(E)-2-{2-[3-chloro-5-(trifluoromethyl)pyridin-2-yl]-2-methylhydrazin-1-yl}ethenyl]-2-oxo-3-[3-(trifluoromethyl)benzamido]-2H-pyran-5-carboxylate is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 590.86 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).
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), Methyl 6-[(E)-2-{2-[3-chloro-5-(trifluoromethyl)pyridin-2-yl]-2-methylhydrazin-1-yl}ethenyl]-2-oxo-3-[3-(trifluoromethyl)benzamido]-2H-pyran-5-carboxylate 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.
