Chemical Structure
Description
As a certified reference material (CRM), 5-Bromo-2,3-dioxo-N-phenylindoline-1-carboxamide 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.
CATO supplies 5-Bromo-2,3-dioxo-N-phenylindoline-1-carboxamide (CAS 53460-53-0), a certified reference material (molecular formula C15H9BrN2O3, MW 345.15 g/mol) for analytical method development and quality control.
Structurally, 5-Bromo-2,3-dioxo-N-phenylindoline-1-carboxamide (C15H9BrN2O3) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, bromine substitution. The molecule exhibits a degree of unsaturation (DBE) of 12.0, corresponding to approximately 12 ring(s) or double-bond equivalent(s). With a molecular weight of 345.15 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.
