Chemical Structure

3-Methoxy-3-oxoprop-1-ene-1-sulfonic acid CAS 1909358-92-4 chemical structure

Description

The occurrence of 3-Methoxy-3-oxoprop-1-ene-1-sulfonic acid is closely related to a carbohydrate-derived structure, a sulfone group, fluorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

3-Methoxy-3-oxoprop-1-ene-1-sulfonic acid (CAS 1909358-92-4), molecular formula C4H5FO4S and molecular weight 168.14 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a carbohydrate-derived structure, a sulfone group, fluorine substitution, 3-Methoxy-3-oxoprop-1-ene-1-sulfonic acid is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 168.14 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.
