Chemical Structure

(Z)-2-fluoro-4-methylpent-2-enoic acid CAS 687-49-0 chemical structure

Description

The occurrence of (Z)-2-fluoro-4-methylpent-2-enoic acid is closely related to a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

(Z)-2-fluoro-4-methylpent-2-enoic acid (CAS 687-49-0), molecular formula C6H9FO2 and molecular weight 132.13 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution, (Z)-2-fluoro-4-methylpent-2-enoic acid is typically white to off-white liquid. Its solid-state physicochemical attributes — including a molecular weight of 132.13 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.
