Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 292.31 g/mol gives Methyl 3-methyl-5-((phenoxycarbonyl)amino)isothiazole-4-carboxylate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies Methyl 3-methyl-5-((phenoxycarbonyl)amino)isothiazole-4-carboxylate (CAS 744973-72-6), a certified reference material (molecular formula C13H12N2O4S, MW 292.31 g/mol) for analytical method development and quality control.
Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, Methyl 3-methyl-5-((phenoxycarbonyl)amino)isothiazole-4-carboxylate is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 292.31 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 Methyl 3-methyl-5-((phenoxycarbonyl)amino)isothiazole-4-carboxylate 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.
