Chemical Structure
Description
5-Phenyl-5,8-dihydroindolo[2,3-c]carbazole (CAS 1637752-63-6), molecular formula C24H16N2 and molecular weight 332.40 g/mol, is a CATO reference standard with documented purity and traceability.
5-Phenyl-5,8-dihydroindolo[2,3-c]carbazole (C24H16N2) contains a nitrogen-containing heterocyclic scaffold, a nitrile group. Its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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.
CATO manufactures 5-Phenyl-5,8-dihydroindolo[2,3-c]carbazole under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
