Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 4-Hydroxy-7-(pyridin-3-yl)-9-(trifluoromethyl)thieno[2,3-b:4,5-b']dipyridin-2(1H)-one.
4-Hydroxy-7-(pyridin-3-yl)-9-(trifluoromethyl)thieno[2,3-b:4,5-b']dipyridin-2(1H)-one (CAS 879457-63-3), molecular formula C16H8F3N3O2S and molecular weight 363.31 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 4-Hydroxy-7-(pyridin-3-yl)-9-(trifluoromethyl)thieno[2,3-b:4,5-b']dipyridin-2(1H)-one (C16H8F3N3O2S) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, fluorine 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), 4-Hydroxy-7-(pyridin-3-yl)-9-(trifluoromethyl)thieno[2,3-b:4,5-b']dipyridin-2(1H)-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.
