1-Bromo-1,1,2,2-tetrafluoro-4-iodobutane CAS 129587-49-1

Description

The occurrence of 1-Bromo-1,1,2,2-tetrafluoro-4-iodobutane is closely related to fluorine/bromine/iodine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

1-Bromo-1,1,2,2-tetrafluoro-4-iodobutane (CAS 129587-49-1) is a high-purity analytical reference standard with the molecular formula C4H4BrF4I and a molecular weight of 334.88 g/mol.

1-Bromo-1,1,2,2-tetrafluoro-4-iodobutane (C4H4BrF4I) contains fluorine/bromine/iodine 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.

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.

As a certified reference material (CRM), 1-Bromo-1,1,2,2-tetrafluoro-4-iodobutane meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
