As a certified reference material (CRM), 2,4-Dichloro-6-methyl-5,6,7,8-tetrahydropyrido[4,3-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.
CATO supplies 2,4-Dichloro-6-methyl-5,6,7,8-tetrahydropyrido[4,3-d]pyrimidine (CAS 1350738-72-5), a certified reference material (molecular formula C8H9Cl2N3, MW 218.08 g/mol) for analytical method development and quality control.
The molecular framework of 2,4-Dichloro-6-methyl-5,6,7,8-tetrahydropyrido[4,3-d]pyrimidine (C8H9Cl2N3) is characterized by a nitrogen-containing heterocyclic scaffold, a nitrile group, 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. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
