(E)-Ethyl 4-Bromo-3-methyl-2-butenoate 51318-62-8 trans-4-Bromo-3-methyl-but-2-enoic Acid Ethyl Ester CAS 51318-62-8 chemical structure

Description

The occurrence of (E)-Ethyl 4-Bromo-3-methyl-2-butenoate 51318-62-8 trans-4-Bromo-3-methyl-but-2-enoic Acid Ethyl Ester 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 (E)-Ethyl 4-Bromo-3-methyl-2-butenoate 51318-62-8 trans-4-Bromo-3-methyl-but-2-enoic Acid Ethyl Ester (CAS 51318-62-8), a certified reference material (molecular formula C7H11BrO2, MW 207.07 g/mol) for analytical method development and quality control.

(E)-Ethyl 4-Bromo-3-methyl-2-butenoate 51318-62-8 trans-4-Bromo-3-methyl-but-2-enoic Acid Ethyl Ester (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.

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.
