Chemical Structure
Description
The occurrence of 3-(3-Bromophenyl)-1-(p-tolyl)propan-1-one is closely related to a hydroxyl group, an ether linkage, bromine substitution, a polycyclic aromatic system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies 3-(3-Bromophenyl)-1-(p-tolyl)propan-1-one (CAS 898781-99-2), a certified reference material (molecular formula C16H15BrO, MW 303.19 g/mol) for analytical method development and quality control.
The molecular framework of 3-(3-Bromophenyl)-1-(p-tolyl)propan-1-one (C16H15BrO) is characterized by a hydroxyl group, an ether linkage, bromine substitution, a polycyclic aromatic system. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), 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.
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), 3-(3-Bromophenyl)-1-(p-tolyl)propan-1-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.
