Ethyl (Z)-4-bromo-3-ethoxybut-2-enoate CAS 65840-69-9

Description

The occurrence of Ethyl (Z)-4-bromo-3-ethoxybut-2-enoate is closely related to a carboxylic acid group, a hydroxyl group, an ether linkage, bromine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies Ethyl (Z)-4-bromo-3-ethoxybut-2-enoate (CAS 65840-69-9), a certified reference material (molecular formula C8H13BrO3, MW 237.09 g/mol) for analytical method development and quality control.

Ethyl (Z)-4-bromo-3-ethoxybut-2-enoate (C8H13BrO3) contains a carboxylic acid group, a hydroxyl group, an ether linkage, bromine substitution. It is notably hygroscopic, 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), Ethyl (Z)-4-bromo-3-ethoxybut-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.
