Chemical Structure

2,7-Dimethoxy-2-methyl-2,3-dihydrobenzo[b][1,4]dioxine CAS 1269447-76-8 chemical structure

Description

The molecular framework of 2,7-Dimethoxy-2-methyl-2,3-dihydrobenzo[b][1,4]dioxine (C11H14O4) 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 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).

2,7-Dimethoxy-2-methyl-2,3-dihydrobenzo[b][1,4]dioxine (CAS 1269447-76-8), molecular formula C11H14O4 and molecular weight 210.23 g/mol, is a CATO reference standard with documented purity and traceability.

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.
