Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 230.60 g/mol gives 2-Chloro-5-((trifluoromethyl)sulfinyl)pyrazine distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
2-Chloro-5-((trifluoromethyl)sulfinyl)pyrazine (CAS 1206524-07-3) is a high-purity analytical reference standard with the molecular formula C5H2ClF3N2OS and a molecular weight of 230.60 g/mol.
The molecular framework of 2-Chloro-5-((trifluoromethyl)sulfinyl)pyrazine (C5H2ClF3N2OS) is characterized by an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, fluorine/chlorine substitution. 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), 2-Chloro-5-((trifluoromethyl)sulfinyl)pyrazine 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.
