(5-Bromo-3-fluoro-2-methoxyphenyl)(methyl)sulfane CAS 2091914-25-7

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including (5-Bromo-3-fluoro-2-methoxyphenyl)(methyl)sulfane.

(5-Bromo-3-fluoro-2-methoxyphenyl)(methyl)sulfane (CAS 2091914-25-7) is a high-purity analytical reference standard with the molecular formula C8H8BrFOS and a molecular weight of 251.12 g/mol.

The molecular framework of (5-Bromo-3-fluoro-2-methoxyphenyl)(methyl)sulfane (C8H8BrFOS) is characterized by sulfur-containing functionality, a hydroxyl group, an ether linkage, fluorine/bromine substitution, an aromatic ring system. 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. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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.
