Chemical Structure
Description
The molecular framework of 2-(5-chloro-2,3-dihydro-1-benzofuran-2-yl)acetic acid (C10H9ClO3) is characterized by a carboxylic acid group, 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).
2-(5-chloro-2,3-dihydro-1-benzofuran-2-yl)acetic acid (CAS 1018251-39-2) is a high-purity analytical reference standard with the molecular formula C10H9ClO3 and a molecular weight of 212.63 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.
