Chemical Structure

1-ethynyl-2-methylcyclohexane CAS 1851913-02-4 chemical structure

Description

1-ethynyl-2-methylcyclohexane (CAS 1851913-02-4), molecular formula C9H14 and molecular weight 122.21 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to an organic framework, 1-ethynyl-2-methylcyclohexane is typically white to off-white liquid. Its solid-state physicochemical attributes — including a molecular weight of 122.21 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.

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.
