Chemical Structure
Description
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.
1-Ethynyl-2,4-difluoro-Benzene 1-ethynyl-2,4-difluorobenzene 302912-34-1 A18602 (CAS 302912-34-1), molecular formula C8H10F2 and molecular weight 144.16 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to fluorine substitution, 1-Ethynyl-2,4-difluoro-Benzene 1-ethynyl-2,4-difluorobenzene 302912-34-1 A18602 is typically white to off-white liquid. Its solid-state physicochemical attributes — including a molecular weight of 144.16 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.
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.
