3,6-Dibromo-9-ethylcarbazole 3,6-dibromo-9-ethyl-9H-carbazole 33255-13-9 CAS 33255-13-9 chemical structure

Description

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.

3,6-Dibromo-9-ethylcarbazole 3,6-dibromo-9-ethyl-9H-carbazole 33255-13-9 (CAS 33255-13-9), molecular formula C14H23Br2N and molecular weight 365.15 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 3,6-Dibromo-9-ethylcarbazole 3,6-dibromo-9-ethyl-9H-carbazole 33255-13-9 (C14H23Br2N) is characterized by a nitrile group, bromine 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).

CATO manufactures 3,6-Dibromo-9-ethylcarbazole 3,6-dibromo-9-ethyl-9H-carbazole 33255-13-9 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.
