Chemical Structure

(Z)-Ethyl 4-Bromo-3-methyl-2-butenoate CAS 51371-55-2 chemical structure

Description

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.

(Z)-Ethyl 4-Bromo-3-methyl-2-butenoate (CAS 51371-55-2) is a high-purity analytical reference standard with the molecular formula C7H11BrO2 and a molecular weight of 207.07 g/mol.

(Z)-Ethyl 4-Bromo-3-methyl-2-butenoate (C7H11BrO2) 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.

As a certified reference material (CRM), (Z)-Ethyl 4-Bromo-3-methyl-2-butenoate 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.
