Chemical Structure
Description
The occurrence of 2,7-Bis(trifluoromethyl)-9H-carbazole is closely related to a nitrogen-containing heterocyclic scaffold, a nitrile group, fluorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
2,7-Bis(trifluoromethyl)-9H-carbazole (CAS 1657076-40-8), molecular formula C14H7F6N and molecular weight 303.20 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 2,7-Bis(trifluoromethyl)-9H-carbazole (C14H7F6N) is characterized by a nitrogen-containing heterocyclic scaffold, a nitrile group, fluorine 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 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.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
