Chemical Structure
Description
The occurrence of 4-Acetoxy-2,3-dichlorobenzophenone is closely related to a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, a polycyclic aromatic system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
4-Acetoxy-2,3-dichlorobenzophenone (CAS 890100-07-9) is a high-purity analytical reference standard with the molecular formula C15H10Cl2O3 and a molecular weight of 309.14 g/mol.
Based on its molecular formula C15H10Cl2O3, 4-Acetoxy-2,3-dichlorobenzophenone 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 309.14 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.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
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.
