Chemical Structure
Description
2,3-Dichloro-3-(1,3-dioxolan-2-yl)benzophenone (CAS 898759-49-4) is a high-purity analytical reference standard with the molecular formula C16H12Cl2O3 and a molecular weight of 323.17 g/mol.
Based on its molecular formula C16H12Cl2O3, 2,3-Dichloro-3-(1,3-dioxolan-2-yl)benzophenone contains 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 323.17 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.
