Chemical Structure
Description
(2,5-dichlorothiophen-3-yl)methanol (CAS 219765-84-1) is a high-purity analytical reference standard with the molecular formula C5H4Cl2OS and a molecular weight of 183.06 g/mol.
The molecular framework of (2,5-dichlorothiophen-3-yl)methanol (C5H4Cl2OS) is characterized by sulfur-containing functionality, a hydroxyl group, an ether linkage, chlorine substitution. 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.
