Chemical Structure
Description
The occurrence of 1-(2,3-Dichlorophenyl)-3-(2-methoxyphenyl)propan-1-one 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.
1-(2,3-Dichlorophenyl)-3-(2-methoxyphenyl)propan-1-one (CAS 898770-48-4) is a high-purity analytical reference standard with the molecular formula C16H14Cl2O2 and a molecular weight of 309.19 g/mol.
Structurally, 1-(2,3-Dichlorophenyl)-3-(2-methoxyphenyl)propan-1-one (C16H14Cl2O2) contains a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, a polycyclic aromatic system. The molecule exhibits a degree of unsaturation (DBE) of 9.0, corresponding to approximately 9 ring(s) or double-bond equivalent(s). With a molecular weight of 309.19 g/mol, it falls into the moderately-high-molecular-weight range. 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).
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.
