Chemical Structure
Description
The occurrence of 9-Chloro-11H-benzo[a]carbazole is closely related to a nitrogen-containing heterocyclic scaffold, a nitrile group, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
9-Chloro-11H-benzo[a]carbazole (CAS 958779-33-4), molecular formula C16H10ClN and molecular weight 251.71 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 9-Chloro-11H-benzo[a]carbazole (C16H10ClN) is characterized by a nitrogen-containing heterocyclic scaffold, a nitrile group, chlorine substitution. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
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 9-Chloro-11H-benzo[a]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.
