Description

The occurrence of 49678-04-8 trans-4-Bromocinnamaldehyde MFCD03032509 trans-3-(4-Bromophenyl)acrolein trans-3-(4-Bromophenyl)acrylaldehyde trans-3-(4-Bromophenyl)-2-propenal 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.

49678-04-8 trans-4-Bromocinnamaldehyde MFCD03032509 trans-3-(4-Bromophenyl)acrolein trans-3-(4-Bromophenyl)acrylaldehyde trans-3-(4-Bromophenyl)-2-propenal (CAS 49678-04-8) is a high-purity analytical reference standard with the molecular formula C9H13BrO and a molecular weight of 217.10 g/mol.

Owing to a hydroxyl group, an ether linkage, bromine substitution, 49678-04-8 trans-4-Bromocinnamaldehyde MFCD03032509 trans-3-(4-Bromophenyl)acrolein trans-3-(4-Bromophenyl)acrylaldehyde trans-3-(4-Bromophenyl)-2-propenal is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 217.10 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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), 49678-04-8 trans-4-Bromocinnamaldehyde MFCD03032509 trans-3-(4-Bromophenyl)acrolein trans-3-(4-Bromophenyl)acrylaldehyde trans-3-(4-Bromophenyl)-2-propenal 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.
