Chemical Structure

Ethyl 2-cycloheptylideneacetate CAS 1903-23-7 chemical structure

Description

The molecular framework of Ethyl 2-cycloheptylideneacetate (C11H18O2) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), 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).

Ethyl 2-cycloheptylideneacetate (CAS 1903-23-7) is a high-purity analytical reference standard with the molecular formula C11H18O2 and a molecular weight of 182.26 g/mol.

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), Ethyl 2-cycloheptylideneacetate 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.
