Description

Compared with other compounds in its class, the molecular weight of 172.23 g/mol gives 4-Cyano-3-hydroxy-5-methylthioisothiazole distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

4-Cyano-3-hydroxy-5-methylthioisothiazole (CAS 4886-02-6), molecular formula C5H4N2OS2 and molecular weight 172.23 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 4-Cyano-3-hydroxy-5-methylthioisothiazole (C5H4N2OS2) is characterized by an amide group, sulfur-containing functionality, 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 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.
