Chemical Structure
Description
6-Chloro-2-(2,6-dichloro-3,5-dimethoxyphenyl)pyrido[3,4-d]pyrimidin-4(3H)-one (CAS 2230975-13-8), molecular formula C15H10Cl3N3O3 and molecular weight 386.62 g/mol, is a CATO reference standard with documented purity and traceability.
6-Chloro-2-(2,6-dichloro-3,5-dimethoxyphenyl)pyrido[3,4-d]pyrimidin-4(3H)-one (C15H10Cl3N3O3) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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), 6-Chloro-2-(2,6-dichloro-3,5-dimethoxyphenyl)pyrido[3,4-d]pyrimidin-4(3H)-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.
