Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
2-(Pyrazin-2-yl)-2-(pyridin-3-yl)thiazolidin-4-one (CAS 89442-25-1) is a high-purity analytical reference standard with the molecular formula C12H10N4OS and a molecular weight of 258.30 g/mol.
The molecular framework of 2-(Pyrazin-2-yl)-2-(pyridin-3-yl)thiazolidin-4-one (C12H10N4OS) is characterized by a nitrogen-containing heterocyclic scaffold, 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 aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
As a certified reference material (CRM), 2-(Pyrazin-2-yl)-2-(pyridin-3-yl)thiazolidin-4-one 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.
