Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 276.31 g/mol gives 4-(9H-Carbazol-9-yl)-3-fluoroaniline distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
4-(9H-Carbazol-9-yl)-3-fluoroaniline (CAS 1820707-85-4), molecular formula C18H13FN2 and molecular weight 276.31 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 4-(9H-Carbazol-9-yl)-3-fluoroaniline (C18H13FN2) 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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.
