Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 285.55 g/mol gives 3,3,4-Trichlorobenzophenone distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
3,3,4-Trichlorobenzophenone (CAS 812684-89-2) is a high-purity analytical reference standard with the molecular formula C13H7Cl3O and a molecular weight of 285.55 g/mol.
Owing to a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system, 3,3,4-Trichlorobenzophenone is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 285.55 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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 3,3,4-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.
