Description
As a certified reference material (CRM), Indolo[2,3-b]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.
CATO supplies Indolo[2,3-b]carbazole (CAS 241-35-0), a certified reference material (molecular formula C18H10N2, MW 254.29 g/mol) for analytical method development and quality control.
Based on its molecular formula C18H10N2, Indolo[2,3-b]carbazole contains a nitrogen-containing heterocyclic scaffold, a nitrile group; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 254.29 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.
