Chemical Structure

1-ethynyl-4-fluoro-cyclohexane CAS 2168016-50-8 chemical structure

Description

As a certified reference material (CRM), 1-ethynyl-4-fluoro-cyclohexane meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.

CATO supplies 1-ethynyl-4-fluoro-cyclohexane (CAS 2168016-50-8), a certified reference material (molecular formula C8H11F, MW 126.17 g/mol) for analytical method development and quality control.

Owing to fluorine substitution, 1-ethynyl-4-fluoro-cyclohexane is typically white to off-white liquid. Its solid-state physicochemical attributes — including a molecular weight of 126.17 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.
