2-(3-Bromophenyl)-2-oxoacetaldehyde CAS 701-37-1 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 2-(3-Bromophenyl)-2-oxoacetaldehyde.

CATO supplies 2-(3-Bromophenyl)-2-oxoacetaldehyde (CAS 701-37-1), a certified reference material (molecular formula C8H5BrO2, MW 213.03 g/mol) for analytical method development and quality control.

Based on its molecular formula C8H5BrO2, 2-(3-Bromophenyl)-2-oxoacetaldehyde contains a carboxylic acid group, a hydroxyl group, an ether linkage, bromine substitution, an aromatic ring system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 213.03 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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), 2-(3-Bromophenyl)-2-oxoacetaldehyde 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.
