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 1-Bromo-3,6-di-tert-butyl-9H-carbazole.
CATO supplies 1-Bromo-3,6-di-tert-butyl-9H-carbazole (CAS 1357359-52-4), a certified reference material (molecular formula C20H24BrN, MW 358.32 g/mol) for analytical method development and quality control.
1-Bromo-3,6-di-tert-butyl-9H-carbazole (C20H24BrN) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, bromine substitution. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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), 1-Bromo-3,6-di-tert-butyl-9H-carbazole 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.
