Chemical Structure

2-Oxo-2-phenylacetyl chloride CAS 25726-04-9 chemical structure

Description

The occurrence of 2-Oxo-2-phenylacetyl chloride is closely related to a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

2-Oxo-2-phenylacetyl chloride (CAS 25726-04-9) is a high-purity analytical reference standard with the molecular formula C8H5ClO2 and a molecular weight of 168.58 g/mol.

The molecular framework of 2-Oxo-2-phenylacetyl chloride (C8H5ClO2) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
