2,4-Dibromothiazole-5-sulfonyl chloride CAS 1359839-37-4

Description

The occurrence of 2,4-Dibromothiazole-5-sulfonyl chloride is closely related to an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine/bromine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

2,4-Dibromothiazole-5-sulfonyl chloride (CAS 1359839-37-4), molecular formula C3Br2ClNO2S2 and molecular weight 341.43 g/mol, is a CATO reference standard with documented purity and traceability.

Based on its molecular formula C3Br2ClNO2S2, 2,4-Dibromothiazole-5-sulfonyl chloride contains an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine/bromine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 341.43 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.
