Chemical Structure
Description
CATO supplies (5-Methoxythiophen-2-yl)methanol (CAS 201598-33-6), a certified reference material (molecular formula C6H8O2S, MW 144.19 g/mol) for analytical method development and quality control.
Owing to a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, (5-Methoxythiophen-2-yl)methanol is typically white to off-white liquid. Its solid-state physicochemical attributes — including a molecular weight of 144.19 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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).
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.
CATO manufactures (5-Methoxythiophen-2-yl)methanol under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
