Chemical Structure

1-ethynyl-1-methylcyclopentane CAS 28509-11-7 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 108.18 g/mol gives 1-ethynyl-1-methylcyclopentane distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

1-ethynyl-1-methylcyclopentane (CAS 28509-11-7) is a high-purity analytical reference standard with the molecular formula C8H12 and a molecular weight of 108.18 g/mol.

Structurally, 1-ethynyl-1-methylcyclopentane (C8H12) 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 108.18 g/mol, it falls into the low-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).

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.

CATO manufactures 1-ethynyl-1-methylcyclopentane under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
