Chemical Structure

Vinyl Acetylene CAS 689-97-4 chemical structure

Description

The occurrence of Vinyl Acetylene is closely related to an organic framework in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

Vinyl Acetylene (CAS 689-97-4) is a high-purity analytical reference standard with the molecular formula C4H4 and a molecular weight of 52.07 g/mol.

The molecular framework of Vinyl Acetylene (C4H4) is characterized by an organic framework. In reversed-phase chromatography, its retention is governed primarily by its non-polar molecular character, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

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.
