Chemical Structure
Description
The molecular framework of 2-chloro-4-methyl-1,5-naphthyridine (C9H17ClN2) is characterized by 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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
2-chloro-4-methyl-1,5-naphthyridine (CAS 1820706-22-6), molecular formula C9H17ClN2 and molecular weight 188.70 g/mol, is a CATO reference standard with documented purity and traceability.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
