Chemical Structure
Description
The molecular framework of Potassium 4-(2,4-dichlorostyryl)-2-pyrimidinethiolate (C12H7Cl2N2SK) is characterized by a salt form, a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality, chlorine substitution. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), 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).
Potassium 4-(2,4-dichlorostyryl)-2-pyrimidinethiolate (CAS 318248-62-3), molecular formula C12H7Cl2N2SK and molecular weight 321.26 g/mol, is a CATO reference standard with documented purity and traceability.
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), Potassium 4-(2,4-dichlorostyryl)-2-pyrimidinethiolate 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.
