Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO supplies Methyl 3-(2,4-dichloropyrido[2,3-d]pyrimidin-7-yl)benzoate (CAS 2004691-97-6), a certified reference material (molecular formula C15H9Cl2N3O2, MW 334.16 g/mol) for analytical method development and quality control.
The molecular framework of Methyl 3-(2,4-dichloropyrido[2,3-d]pyrimidin-7-yl)benzoate (C15H9Cl2N3O2) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine 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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
As a certified reference material (CRM), Methyl 3-(2,4-dichloropyrido[2,3-d]pyrimidin-7-yl)benzoate 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.
