Chemical Structure
Description
The occurrence of 2-Bromoacrylaldehyde is closely related to a hydroxyl group, an ether linkage, bromine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies 2-Bromoacrylaldehyde (CAS 14925-39-4), a certified reference material (molecular formula C3H3BrO, MW 134.96 g/mol) for analytical method development and quality control.
Based on its molecular formula C3H3BrO, 2-Bromoacrylaldehyde contains a hydroxyl group, an ether linkage, bromine substitution; these features give the compound characteristic functional-group stretching vibrations in infrared spectroscopy. The molecular weight of 134.96 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-Bromoacrylaldehyde 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.
