Chemical Structure

4,6,8-Trimethylazulene CAS 941-81-1 chemical structure

Description

The occurrence of 4,6,8-Trimethylazulene is closely related to an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies 4,6,8-Trimethylazulene (CAS 941-81-1), a certified reference material (molecular formula C13H14, MW 170.25 g/mol) for analytical method development and quality control.

The molecular framework of 4,6,8-Trimethylazulene (C13H14) is characterized by an aromatic ring system. 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.

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.
