Description
CATO supplies 4-Chloro-N-(2-{11,15-dioxa-16-azatetracyclo[8.7.0.0^{2,7}.0^{13,17}]heptadeca-1(10),2(7),3,5,8-pentaen-16-yl}-2-oxoethyl)benzamide (CAS 477853-82-0), a certified reference material (molecular formula C23H19ClN2O4, MW 422.86 g/mol) for analytical method development and quality control.
Structurally, 4-Chloro-N-(2-{11,15-dioxa-16-azatetracyclo[8.7.0.0^{2,7}.0^{13,17}]heptadeca-1(10),2(7),3,5,8-pentaen-16-yl}-2-oxoethyl)benzamide (C23H19ClN2O4) contains a flavonoid core, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 15.0, corresponding to approximately 15 ring(s) or double-bond equivalent(s). With a molecular weight of 422.86 g/mol, it falls into the moderately-high-molecular-weight range. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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), 4-Chloro-N-(2-{11,15-dioxa-16-azatetracyclo[8.7.0.0^{2,7}.0^{13,17}]heptadeca-1(10),2(7),3,5,8-pentaen-16-yl}-2-oxoethyl)benzamide 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.
