Chemical Structure

1,2-dibromopentane CAS 3234-49-9 chemical structure

Description

As a certified reference material (CRM), 1,2-dibromopentane 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.

1,2-dibromopentane (CAS 3234-49-9) is a high-purity analytical reference standard with the molecular formula C5H10Br2 and a molecular weight of 229.94 g/mol.

1,2-dibromopentane (C5H10Br2) 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.
