(4-Amino-3-methylthieno[2,3-c]isothiazol-5-yl)(4-methoxyphenyl)methanone CAS 339017-38-8

Description

Compared with other compounds in its class, the molecular weight of 304.39 g/mol gives (4-Amino-3-methylthieno[2,3-c]isothiazol-5-yl)(4-methoxyphenyl)methanone distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies (4-Amino-3-methylthieno[2,3-c]isothiazol-5-yl)(4-methoxyphenyl)methanone (CAS 339017-38-8), a certified reference material (molecular formula C14H12N2O2S2, MW 304.39 g/mol) for analytical method development and quality control.

The molecular framework of (4-Amino-3-methylthieno[2,3-c]isothiazol-5-yl)(4-methoxyphenyl)methanone (C14H12N2O2S2) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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).

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
