Chemical Structure

1,9-Dimethyl-7-ethylphenanthrene CAS 46870-52-4 chemical structure

Description

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.

1,9-Dimethyl-7-ethylphenanthrene (CAS 46870-52-4) is a high-purity analytical reference standard with the molecular formula C18H18 and a molecular weight of 234.34 g/mol.

1,9-Dimethyl-7-ethylphenanthrene (C18H18) contains a polycyclic aromatic system. Its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

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.
