Chemical Structure
Description
CATO supplies 7-Iodo-3,3-dimethyl-3,4-dihydropyrido[2,3-b]pyrazin-2(1H)-one (CAS 957194-64-8), a certified reference material (molecular formula C9H10IN3O, MW 303.10 g/mol) for analytical method development and quality control.
7-Iodo-3,3-dimethyl-3,4-dihydropyrido[2,3-b]pyrazin-2(1H)-one (C9H10IN3O) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, iodine substitution. Halogen substitution raises its density and boiling point; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
As a certified reference material (CRM), 7-Iodo-3,3-dimethyl-3,4-dihydropyrido[2,3-b]pyrazin-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.
