Chemical Structure

9-(2-ethylhexyl)carbazole CAS 187148-77-2 chemical structure

Description

9-(2-ethylhexyl)carbazole (C20H37N) contains a nitrile group. Its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

9-(2-ethylhexyl)carbazole (CAS 187148-77-2) is a high-purity analytical reference standard with the molecular formula C20H37N and a molecular weight of 291.51 g/mol.

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.
