Chemical Structure
Description
The molecular framework of 7,11-Dimethyl-3-octyl-1,3,8,12-tetraazatricyclo[7.3.0.0^{2,6}]dodeca-2(6),7,9,11-tetraene (C18H28N4) is characterized by a nitrogen-containing heterocyclic scaffold, a nitrile group. 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 high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
7,11-Dimethyl-3-octyl-1,3,8,12-tetraazatricyclo[7.3.0.0^{2,6}]dodeca-2(6),7,9,11-tetraene (CAS 866137-19-1) is a high-purity analytical reference standard with the molecular formula C18H28N4 and a molecular weight of 300.44 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.
