Chemical Structure
Description
Owing to fluorine substitution, 1-Ethynyl-1-(fluoromethyl)cyclopropane is typically white to off-white liquid. Its solid-state physicochemical attributes — including a molecular weight of 98.12 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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).
1-Ethynyl-1-(fluoromethyl)cyclopropane (CAS 2228783-15-9) is a high-purity analytical reference standard with the molecular formula C6H7F and a molecular weight of 98.12 g/mol.
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.
