Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 186.26 g/mol gives 5-Hydrazinyl-3-(methylthio)isothiazole-4-carbonitrile distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
5-Hydrazinyl-3-(methylthio)isothiazole-4-carbonitrile (CAS 29231-68-3) is a high-purity analytical reference standard with the molecular formula C5H6N4S2 and a molecular weight of 186.26 g/mol.
The molecular framework of 5-Hydrazinyl-3-(methylthio)isothiazole-4-carbonitrile (C5H6N4S2) is characterized by a nitrile group, sulfur-containing functionality. 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.
As a certified reference material (CRM), 5-Hydrazinyl-3-(methylthio)isothiazole-4-carbonitrile 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.
