Description

Compared with other compounds in its class, the molecular weight of 244.27 g/mol gives Diethyl 4-aminoisothiazole-3,5-dicarboxylate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

Diethyl 4-aminoisothiazole-3,5-dicarboxylate (CAS 72632-87-2), molecular formula C9H12N2O4S and molecular weight 244.27 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of Diethyl 4-aminoisothiazole-3,5-dicarboxylate (C9H12N2O4S) 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 the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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 Diethyl 4-aminoisothiazole-3,5-dicarboxylate 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.
