Chemical Structure

Ethyl (E)-3-ethoxy-2-butenoate CAS 57592-45-7 chemical structure

Description

The occurrence of Ethyl (E)-3-ethoxy-2-butenoate is closely related to a carboxylic acid group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

Ethyl (E)-3-ethoxy-2-butenoate (CAS 57592-45-7) is a high-purity analytical reference standard with the molecular formula C8H14O3 and a molecular weight of 158.19 g/mol.

Ethyl (E)-3-ethoxy-2-butenoate (C8H14O3) contains a carboxylic acid group, a hydroxyl group, an ether linkage. It is notably hygroscopic, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions.

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.

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
