2,3-Dibromobutanoyl chloride CAS 51356-48-0

Description

Compared with other compounds in its class, the molecular weight of 264.34 g/mol gives 2,3-Dibromobutanoyl chloride distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies 2,3-Dibromobutanoyl chloride (CAS 51356-48-0), a certified reference material (molecular formula C4H5Br2ClO, MW 264.34 g/mol) for analytical method development and quality control.

The molecular framework of 2,3-Dibromobutanoyl chloride (C4H5Br2ClO) is characterized by a hydroxyl group, an ether linkage, chlorine/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.

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
