Chemical Structure
Description
2,4,7-trichloropyrido[3,2-d]pyrimidine (CAS 1260663-38-4), molecular formula C7H12Cl3N3 and molecular weight 244.55 g/mol, is a CATO reference standard with documented purity and traceability.
2,4,7-trichloropyrido[3,2-d]pyrimidine (C7H12Cl3N3) contains a nitrile group, chlorine substitution. Halogen substitution raises its density and boiling point; 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), 2,4,7-trichloropyrido[3,2-d]pyrimidine 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.
