Chemical Structure

3-(7-Chlorobenzo[d][1,3]dioxol-5-yl)-2-oxopropanoic acid CAS 1153355-02-2 chemical structure

Description

The occurrence of 3-(7-Chlorobenzo[d][1,3]dioxol-5-yl)-2-oxopropanoic acid is closely related to a carboxylic acid group, 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.

3-(7-Chlorobenzo[d][1,3]dioxol-5-yl)-2-oxopropanoic acid (CAS 1153355-02-2) is a high-purity analytical reference standard with the molecular formula C10H7ClO5 and a molecular weight of 242.61 g/mol.

The molecular framework of 3-(7-Chlorobenzo[d][1,3]dioxol-5-yl)-2-oxopropanoic acid (C10H7ClO5) 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 the polarity and ionization state of its functional groups, 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.
