Chemical Structure
Description
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.
Methyl 3-[(2-chloro-1,3-thiazol-5-yl)methoxy]-2-thiophenecarboxylate (CAS 478246-26-3) is a high-purity analytical reference standard with the molecular formula C10H8ClNO3S2 and a molecular weight of 289.76 g/mol.
Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine substitution, Methyl 3-[(2-chloro-1,3-thiazol-5-yl)methoxy]-2-thiophenecarboxylate is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 289.76 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).
CATO manufactures Methyl 3-[(2-chloro-1,3-thiazol-5-yl)methoxy]-2-thiophenecarboxylate 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.
