Chemical Structure

1-Bromo-2-fluoro-2-methylpropane CAS 19869-78-4 chemical structure

Description

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.

1-Bromo-2-fluoro-2-methylpropane (CAS 19869-78-4), molecular formula C4H8BrF and molecular weight 155.01 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, 1-Bromo-2-fluoro-2-methylpropane (C4H8BrF) contains fluorine/bromine substitution. The molecule exhibits a degree of unsaturation (DBE) of 0.0, corresponding to approximately 0 ring(s) or double-bond equivalent(s). With a molecular weight of 155.01 g/mol, it falls into the medium-molecular-weight range. 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.
