Methyl 5-methylisothiazole-4-carboxylate CAS 15901-70-9

Description

Compared with other compounds in its class, the molecular weight of 157.19 g/mol gives Methyl 5-methylisothiazole-4-carboxylate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies Methyl 5-methylisothiazole-4-carboxylate (CAS 15901-70-9), a certified reference material (molecular formula C6H7NO2S, MW 157.19 g/mol) for analytical method development and quality control.

Based on its molecular formula C6H7NO2S, Methyl 5-methylisothiazole-4-carboxylate contains an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 157.19 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.

As a certified reference material (CRM), Methyl 5-methylisothiazole-4-carboxylate meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
