Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 7-Bromo-2-iodo-1H-indole.
CATO supplies 7-Bromo-2-iodo-1H-indole (CAS 1904650-74-3), a certified reference material (molecular formula C8H5BrIN, MW 321.94 g/mol) for analytical method development and quality control.
7-Bromo-2-iodo-1H-indole (C8H5BrIN) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, bromine/iodine substitution. Halogen substitution raises its density and boiling point; 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), 7-Bromo-2-iodo-1H-indole 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.
