Chemical Structure

methyl 4-bromo-3-methylbut-2-enoate CAS 19041-17-9 chemical structure

Description

CATO supplies methyl 4-bromo-3-methylbut-2-enoate (CAS 19041-17-9), a certified reference material (molecular formula C6H9BrO2, MW 193.04 g/mol) for analytical method development and quality control.

methyl 4-bromo-3-methylbut-2-enoate (C6H9BrO2) contains a carboxylic acid group, a hydroxyl group, an ether linkage, bromine substitution. Halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; 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.

As a certified reference material (CRM), methyl 4-bromo-3-methylbut-2-enoate 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.
