Description
As a certified reference material (CRM), 4,6-Dichloro-2-(dimethylamino)pyrimidine-5-carbaldehyde 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.
4,6-Dichloro-2-(dimethylamino)pyrimidine-5-carbaldehyde (CAS 15138-41-7), molecular formula C7H7Cl2N3O and molecular weight 220.06 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 4,6-Dichloro-2-(dimethylamino)pyrimidine-5-carbaldehyde (C7H7Cl2N3O) is characterized by an amide group, a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system. 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.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
