Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 3-Bromo-2-(difluoromethoxy)thiophenol.
3-Bromo-2-(difluoromethoxy)thiophenol (CAS 1805528-05-5) is a high-purity analytical reference standard with the molecular formula C7H5BrF2OS and a molecular weight of 255.08 g/mol.
The molecular framework of 3-Bromo-2-(difluoromethoxy)thiophenol (C7H5BrF2OS) 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 presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
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.
