Description

Compared with other compounds in its class, the molecular weight of 225.49 g/mol gives 4-Bromo-2-thiophenecarbonyl chloride 4-bromothiophene-2-carbonyl chloride 58777-65-4 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

4-Bromo-2-thiophenecarbonyl chloride 4-bromothiophene-2-carbonyl chloride 58777-65-4 (CAS 58777-65-4) is a high-purity analytical reference standard with the molecular formula C5H2BrClOS and a molecular weight of 225.49 g/mol.

4-Bromo-2-thiophenecarbonyl chloride 4-bromothiophene-2-carbonyl chloride 58777-65-4 (C5H2BrClOS) contains sulfur-containing functionality, a hydroxyl group, an ether linkage, chlorine/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.

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.
