1,3-Dibromobuta-1,2-Diene CAS 138777-52-3

Description

Compared with other compounds in its class, the molecular weight of 211.88 g/mol gives 1,3-Dibromobuta-1,2-Diene distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

1,3-Dibromobuta-1,2-Diene (CAS 138777-52-3) is a high-purity analytical reference standard with the molecular formula C4H4Br2 and a molecular weight of 211.88 g/mol.

The molecular framework of 1,3-Dibromobuta-1,2-Diene (C4H4Br2) is characterized by bromine substitution. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.
