Chemical Structure

Methyl (e)-4-chloro-2-methylbut-2-enoate CAS 56905-07-8 chemical structure

Description

The occurrence of Methyl (e)-4-chloro-2-methylbut-2-enoate is closely related to a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

Methyl (e)-4-chloro-2-methylbut-2-enoate (CAS 56905-07-8) is a high-purity analytical reference standard with the molecular formula C6H9ClO2 and a molecular weight of 148.59 g/mol.

The molecular framework of Methyl (e)-4-chloro-2-methylbut-2-enoate (C6H9ClO2) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.
