5-(2-{[3-chloro-5-(trifluoromethyl)pyridin-2-yl]amino}ethyl)-3-(3-methyl-5-oxo-1-phenyl-1,2,4-triazolidin-3-yl)-3aH,4H,5H,6H,6aH-pyrrolo[3,4-d][1,2]oxazole-4,6-dione CAS 317822-46-1

Description

The occurrence of 5-(2-{[3-chloro-5-(trifluoromethyl)pyridin-2-yl]amino}ethyl)-3-(3-methyl-5-oxo-1-phenyl-1,2,4-triazolidin-3-yl)-3aH,4H,5H,6H,6aH-pyrrolo[3,4-d][1,2]oxazole-4,6-dione is closely related to a flavonoid core, an amide group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

5-(2-{[3-chloro-5-(trifluoromethyl)pyridin-2-yl]amino}ethyl)-3-(3-methyl-5-oxo-1-phenyl-1,2,4-triazolidin-3-yl)-3aH,4H,5H,6H,6aH-pyrrolo[3,4-d][1,2]oxazole-4,6-dione (CAS 317822-46-1), molecular formula C22H19ClF3N7O4 and molecular weight 537.88 g/mol, is a CATO reference standard with documented purity and traceability.

5-(2-{[3-chloro-5-(trifluoromethyl)pyridin-2-yl]amino}ethyl)-3-(3-methyl-5-oxo-1-phenyl-1,2,4-triazolidin-3-yl)-3aH,4H,5H,6H,6aH-pyrrolo[3,4-d][1,2]oxazole-4,6-dione (C22H19ClF3N7O4) contains a flavonoid core, an amide group, a hydroxyl group, an ether linkage, fluorine/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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

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), 5-(2-{[3-chloro-5-(trifluoromethyl)pyridin-2-yl]amino}ethyl)-3-(3-methyl-5-oxo-1-phenyl-1,2,4-triazolidin-3-yl)-3aH,4H,5H,6H,6aH-pyrrolo[3,4-d][1,2]oxazole-4,6-dione 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.
