Chemical Structure
Description
CATO supplies 3-Chlorothiophene-2-methanol (CAS 193602-41-4), a certified reference material (molecular formula C5H5ClOS, MW 148.61 g/mol) for analytical method development and quality control.
The molecular framework of 3-Chlorothiophene-2-methanol (C5H5ClOS) 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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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.
