2,4-DIBROMOBUTANOYL CHLORIDE 2,4-DIBROMOBUTYRYL CHLORIDE 82820-87-9 BC004825 BUTANOYL CHLORIDE, 2,4-DIBROMO- CAS 82820-87-9 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 264.34 g/mol gives 2,4-DIBROMOBUTANOYL CHLORIDE 2,4-DIBROMOBUTYRYL CHLORIDE 82820-87-9 BC004825 BUTANOYL CHLORIDE, 2,4-DIBROMO- distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

2,4-DIBROMOBUTANOYL CHLORIDE 2,4-DIBROMOBUTYRYL CHLORIDE 82820-87-9 BC004825 BUTANOYL CHLORIDE, 2,4-DIBROMO- (CAS 82820-87-9) is a high-purity analytical reference standard with the molecular formula C4H5Br2ClO and a molecular weight of 264.34 g/mol.

Based on its molecular formula C4H5Br2ClO, 2,4-DIBROMOBUTANOYL CHLORIDE 2,4-DIBROMOBUTYRYL CHLORIDE 82820-87-9 BC004825 BUTANOYL CHLORIDE, 2,4-DIBROMO- contains a hydroxyl group, an ether linkage, chlorine/bromine substitution; these features give the compound characteristic functional-group stretching vibrations in infrared spectroscopy. The molecular weight of 264.34 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.
