Chemical Structure
Description
The occurrence of 2,7-Diphenyl-9H-carbazole is closely related to a nitrogen-containing heterocyclic scaffold, a nitrile group in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
2,7-Diphenyl-9H-carbazole (CAS 42448-04-4), molecular formula C24H17N and molecular weight 319.40 g/mol, is a CATO reference standard with documented purity and traceability.
2,7-Diphenyl-9H-carbazole (C24H17N) 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 aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO manufactures 2,7-Diphenyl-9H-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.
