Description

Compared with other compounds in its class, the molecular weight of 277.20 g/mol gives 4-Bromo-2-(1,3-dithiolan-2-yl)phenol distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

4-Bromo-2-(1,3-dithiolan-2-yl)phenol (CAS 175276-78-5), molecular formula C9H9BrOS2 and molecular weight 277.20 g/mol, is a CATO reference standard with documented purity and traceability.

Based on its molecular formula C9H9BrOS2, 4-Bromo-2-(1,3-dithiolan-2-yl)phenol contains sulfur-containing functionality, a hydroxyl group, an ether linkage, bromine substitution, an aromatic ring system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 277.20 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.
