Description
As a certified reference material (CRM), 4-(4-Fluorostyryl)cinnoline 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.
4-(4-Fluorostyryl)cinnoline (CAS 5387-94-0), molecular formula C11H16N2OSHCl and molecular weight 260.78 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 4-(4-Fluorostyryl)cinnoline (C11H16N2OSHCl) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, 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).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
