Chemical Structure

2-Ethyltoluene CAS 611-14-3 chemical structure

Description

The occurrence of 2-Ethyltoluene is closely related to an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

2-Ethyltoluene (CAS 611-14-3) is a high-purity analytical reference standard with the molecular formula C9H12 and a molecular weight of 120.19 g/mol.

The molecular framework of 2-Ethyltoluene (C9H12) is characterized by an aromatic ring system. In reversed-phase chromatography, its retention is governed primarily by its non-polar molecular character, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.
