Chemical Structure

5-Chloro-7-(chloromethyl)-2,2-dimethyl-2,3-dihydrobenzofuran CAS 1234844-89-3 chemical structure

Description

The occurrence of 5-Chloro-7-(chloromethyl)-2,2-dimethyl-2,3-dihydrobenzofuran is closely related to a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies 5-Chloro-7-(chloromethyl)-2,2-dimethyl-2,3-dihydrobenzofuran (CAS 1234844-89-3), a certified reference material (molecular formula C11H12Cl2O, MW 231.12 g/mol) for analytical method development and quality control.

The molecular framework of 5-Chloro-7-(chloromethyl)-2,2-dimethyl-2,3-dihydrobenzofuran (C11H12Cl2O) is characterized by a hydroxyl group, an ether linkage, chlorine substitution, 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).

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.

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
