Chemical Structure

2-(2-(3,4-Dichlorophenoxy)ethyl)-1,3-dioxolane CAS 1225797-71-6 chemical structure

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 2-(2-(3,4-Dichlorophenoxy)ethyl)-1,3-dioxolane.

2-(2-(3,4-Dichlorophenoxy)ethyl)-1,3-dioxolane (CAS 1225797-71-6) is a high-purity analytical reference standard with the molecular formula C11H12Cl2O3 and a molecular weight of 263.12 g/mol.

Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system, 2-(2-(3,4-Dichlorophenoxy)ethyl)-1,3-dioxolane is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 263.12 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.

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.
