Chemical Structure

1,5-dibromopent-2-ene CAS 58673-29-3 chemical structure

Description

The occurrence of 1,5-dibromopent-2-ene is closely related to bromine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

1,5-dibromopent-2-ene (CAS 58673-29-3), molecular formula C5H8Br2 and molecular weight 227.93 g/mol, is a CATO reference standard with documented purity and traceability.

1,5-dibromopent-2-ene (C5H8Br2) contains 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.

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), 1,5-dibromopent-2-ene 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.
