Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 1-(3-bromo-5-chlorophenyl)ethan-1-one.
CATO supplies 1-(3-bromo-5-chlorophenyl)ethan-1-one (CAS 154257-85-9), a certified reference material (molecular formula C8H12BrClO, MW 239.54 g/mol) for analytical method development and quality control.
Owing to a hydroxyl group, an ether linkage, chlorine/bromine substitution, 1-(3-bromo-5-chlorophenyl)ethan-1-one is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 239.54 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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), 1-(3-bromo-5-chlorophenyl)ethan-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.
