Chemical Structure

Trans-2-ethynylcycloheptanol CAS 25127-83-7 chemical structure

Description

Trans-2-ethynylcycloheptanol (CAS 25127-83-7), molecular formula C9H14O and molecular weight 138.21 g/mol, is a CATO reference standard with documented purity and traceability.

Based on its molecular formula C9H14O, Trans-2-ethynylcycloheptanol contains a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 138.21 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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 Trans-2-ethynylcycloheptanol 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.
