Chemical Structure

3,4-Dimethoxy-6,7,8,9,10,10a-hexahydro-5aH-cyclohepta[b]benzofuran CAS 16958-56-8 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 248.32 g/mol gives 3,4-Dimethoxy-6,7,8,9,10,10a-hexahydro-5aH-cyclohepta[b]benzofuran distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

3,4-Dimethoxy-6,7,8,9,10,10a-hexahydro-5aH-cyclohepta[b]benzofuran (CAS 16958-56-8), molecular formula C15H20O3 and molecular weight 248.32 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 3,4-Dimethoxy-6,7,8,9,10,10a-hexahydro-5aH-cyclohepta[b]benzofuran (C15H20O3) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system. 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 high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

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), 3,4-Dimethoxy-6,7,8,9,10,10a-hexahydro-5aH-cyclohepta[b]benzofuran 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.
