Chemical Structure

2-(Methylthio)thiazolo[4,5-b]pyrazine CAS 87444-23-3 chemical structure

Description

The molecular framework of 2-(Methylthio)thiazolo[4,5-b]pyrazine (C6H5N3S2) is characterized by a nitrile group, sulfur-containing functionality, an aromatic ring system. 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).

2-(Methylthio)thiazolo[4,5-b]pyrazine (CAS 87444-23-3) is a high-purity analytical reference standard with the molecular formula C6H5N3S2 and a molecular weight of 183.25 g/mol.

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