1-Bromo-1,2-difluoro-1,4-pentadiene CAS 1730-24-1

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-Bromo-1,2-difluoro-1,4-pentadiene (CAS 1730-24-1) is a high-purity analytical reference standard with the molecular formula C5H5BrF2 and a molecular weight of 182.99 g/mol.

1-Bromo-1,2-difluoro-1,4-pentadiene (C5H5BrF2) contains fluorine/bromine substitution. Halogen substitution raises its density and boiling point; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
