Chemical Structure

5-BRomo-1,1,1,2,2,3,3-heptafluoropentane CAS 355-94-2 chemical structure

Description

CATO supplies 5-BRomo-1,1,1,2,2,3,3-heptafluoropentane (CAS 355-94-2), a certified reference material (molecular formula C5H4BrF7, MW 276.98 g/mol) for analytical method development and quality control.

Based on its molecular formula C5H4BrF7, 5-BRomo-1,1,1,2,2,3,3-heptafluoropentane contains fluorine/bromine substitution; these features give the compound characteristic molecular-ion distribution patterns in mass spectrometry. The molecular weight of 276.98 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.
