Description
CATO supplies 5,6,7,8-Tetrahydropyrido[3,4-d]pyrimidin-2-amine dihydrochloride (CAS 1820703-96-5), a certified reference material (molecular formula C7H10N4HCl, MW 186.64 g/mol) for analytical method development and quality control.
The molecular framework of 5,6,7,8-Tetrahydropyrido[3,4-d]pyrimidin-2-amine dihydrochloride (C7H10N4HCl) is characterized by a nitrile group, 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.
As a certified reference material (CRM), 5,6,7,8-Tetrahydropyrido[3,4-d]pyrimidin-2-amine dihydrochloride 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.
