Chemical Structure
Description
(2-Methoxythiazol-5-yl)methanol (CAS 937676-12-5) is a high-purity analytical reference standard with the molecular formula C5H7NO2S and a molecular weight of 145.18 g/mol.
Owing to an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, (2-Methoxythiazol-5-yl)methanol is typically white to pale yellow liquid. Its solid-state physicochemical attributes — including a molecular weight of 145.18 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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 (2-Methoxythiazol-5-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.
