Chemical Structure

1-ethynyl-4-(propan-2-yl)cyclohexane CAS 1866646-62-9 chemical structure

Description

Structurally, 1-ethynyl-4-(propan-2-yl)cyclohexane (C11H18) contains an organic framework. The molecule exhibits a degree of unsaturation (DBE) of 3.0, corresponding to approximately 3 ring(s) or double-bond equivalent(s). With a molecular weight of 150.26 g/mol, it falls into the medium-molecular-weight range. 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).

1-ethynyl-4-(propan-2-yl)cyclohexane (CAS 1866646-62-9) is a high-purity analytical reference standard with the molecular formula C11H18 and a molecular weight of 150.26 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.
