Chemical Structure
Description
CATO supplies 9-(4-Aminophenyl)-9h-carbazole-3,6-diamine (CAS 75773-11-4), a certified reference material (molecular formula C18H16N4, MW 288.35 g/mol) for analytical method development and quality control.
Structurally, 9-(4-Aminophenyl)-9h-carbazole-3,6-diamine (C18H16N4) contains a nitrogen-containing heterocyclic scaffold, a nitrile group. The molecule exhibits a degree of unsaturation (DBE) of 13.0, corresponding to approximately 13 ring(s) or double-bond equivalent(s). With a molecular weight of 288.35 g/mol, it falls into the medium-molecular-weight range. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
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.
