1-ethynyl-1-methyl-cyclohexane CAS 28509-10-6

Description

1-ethynyl-1-methyl-cyclohexane (CAS 28509-10-6), molecular formula C9H14 and molecular weight 122.21 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 1-ethynyl-1-methyl-cyclohexane (C9H14) is characterized by an organic framework. 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 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.

As a certified reference material (CRM), 1-ethynyl-1-methyl-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.
