Chemical Structure
Description
5-Bromo-4-chloro-4,5,5-trifluoropent-2-en-1-ol (CAS 232602-81-2), molecular formula C5H5BrClF3O and molecular weight 253.44 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, 5-Bromo-4-chloro-4,5,5-trifluoropent-2-en-1-ol (C5H5BrClF3O) contains a hydroxyl group, an ether linkage, fluorine/chlorine/bromine substitution. The molecule exhibits a degree of unsaturation (DBE) of 1.0, corresponding to approximately 1 ring(s) or double-bond equivalent(s). With a molecular weight of 253.44 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.
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.
