Chemical Structure

1-Bromo-3-(4-chlorophenyl)propan-2-one CAS 103557-35-3 chemical structure

Description

The occurrence of 1-Bromo-3-(4-chlorophenyl)propan-2-one is closely related to a hydroxyl group, an ether linkage, chlorine/bromine substitution, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

1-Bromo-3-(4-chlorophenyl)propan-2-one (CAS 103557-35-3), molecular formula C9H8BrClO and molecular weight 247.52 g/mol, is a CATO reference standard with documented purity and traceability.

1-Bromo-3-(4-chlorophenyl)propan-2-one (C9H8BrClO) contains a hydroxyl group, an ether linkage, chlorine/bromine substitution, an aromatic ring system. Halogen substitution raises its density and boiling point; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.

As a certified reference material (CRM), 1-Bromo-3-(4-chlorophenyl)propan-2-one meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
