Chemical Structure

4-Bromobut-2-enamide CAS 118941-93-8 chemical structure

Description

As a certified reference material (CRM), 4-Bromobut-2-enamide 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.

4-Bromobut-2-enamide (CAS 118941-93-8) is a high-purity analytical reference standard with the molecular formula C4H6BrNO and a molecular weight of 164.00 g/mol.

4-Bromobut-2-enamide (C4H6BrNO) contains an amide group, a hydroxyl group, an ether linkage, bromine substitution. Halogen substitution raises its density and boiling point; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
