Chemical Structure

2,3',5'-Trichlorobenzophenone CAS 951889-95-5 chemical structure

Description

The occurrence of 2,3',5'-Trichlorobenzophenone is closely related to 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.

CATO supplies 2,3',5'-Trichlorobenzophenone (CAS 951889-95-5), a certified reference material (molecular formula C13H7Cl3O, MW 285.55 g/mol) for analytical method development and quality control.

Based on its molecular formula C13H7Cl3O, 2,3',5'-Trichlorobenzophenone contains a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 285.55 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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).

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.

CATO manufactures 2,3',5'-Trichlorobenzophenone under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
