Chemical Structure

Ethyl (Z)-3-Iodo-2-butenoate CAS 34450-62-9 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 240.04 g/mol gives Ethyl (Z)-3-Iodo-2-butenoate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

Ethyl (Z)-3-Iodo-2-butenoate (CAS 34450-62-9) is a high-purity analytical reference standard with the molecular formula C6H9IO2 and a molecular weight of 240.04 g/mol.

Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, iodine substitution, Ethyl (Z)-3-Iodo-2-butenoate is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 240.04 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.

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.
