Chemical Structure

5-Bromopent-2-ene CAS 51952-42-2 chemical structure

Description

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

5-Bromopent-2-ene (CAS 51952-42-2), molecular formula C5H9Br and molecular weight 149.03 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to bromine substitution, 5-Bromopent-2-ene is typically white to off-white liquid. Its solid-state physicochemical attributes — including a molecular weight of 149.03 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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), 5-Bromopent-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.
