Chemical Structure
Description
The occurrence of 2,2-Dichloro-1,2-diphenylethan-1-one is closely related to 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.
2,2-Dichloro-1,2-diphenylethan-1-one (CAS 31315-51-2) is a high-purity analytical reference standard with the molecular formula C14H10Cl2O and a molecular weight of 265.13 g/mol.
Owing to a hydroxyl group, an ether linkage, chlorine substitution, a polycyclic aromatic system, 2,2-Dichloro-1,2-diphenylethan-1-one is typically pale yellow to yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 265.13 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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.
