2-(2,4-Dichlorobenzoyl)-5-(1,3-dioxolan-2-yl)thiophene CAS 898778-88-6 chemical structure

Description

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.

2-(2,4-Dichlorobenzoyl)-5-(1,3-dioxolan-2-yl)thiophene (CAS 898778-88-6), molecular formula C14H10Cl2O3S and molecular weight 329.20 g/mol, is a CATO reference standard with documented purity and traceability.

Based on its molecular formula C14H10Cl2O3S, 2-(2,4-Dichlorobenzoyl)-5-(1,3-dioxolan-2-yl)thiophene contains a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, a polycyclic aromatic system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 329.20 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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.
